Last month, Alto celebrated the well-deserved promotions of many Altoids across the company. Among those promoted is Elnaz Moshfeghian, who is now Alto’s VP of Strategic Planning & Business Operations.

Elnaz joined Alto in 2016 as a software engineer and when we last connected with her in 2020, she shared her thoughts on building a career in engineering. Since then, Elnaz has pivoted to a truly cross functional, strategy-focused role, where she applies learnings from her engineering experience with her ability to identify opportunities for growth. 

Below, Elnaz shares more about her new role, what she’s most excited about at Alto, and advice she has for those looking to make a career pivot.  

To start, congratulations on your new role! You joined Alto 6.5 years ago, and so much has changed both within the company and the industry at large. Can you tell me a little bit about your journey at Alto? 

I’ve always been attracted to problems that are cross functional and can be solved by bringing together different teams - pharmacists, technicians, logistics, dispatch, sales. I really enjoyed it as an engineer, given that when I joined there were no product managers. We all had to figure out what we were going to build and build it ourselves. I loved working with teams, which is why I pursued the manager track. I noticed pretty quickly that the most interesting and challenging problems rarely came down to technical decisions, but more-so to people and priorities. 

As I grew in my engineering career, and got to lead teams solving problems, I was always searching for how to expand my understanding and impact across the business. I had the opportunity to shift into a strategy and operations role, which allowed me to shadow the CEO and learn a great deal while also identifying the company’s key priorities, understanding how they're doing, and ensuring that they stay on track. The new role allows me to use everything I’ve learned over the last 6.5 years at the company while at the same time, learning a lot from a seasoned leader like Alicia on how to run a business. 

Your previous experience was in engineering, and you didn’t work in healthcare or pharma before joining Alto. What has been the biggest surprise to you since joining the company? 

There are a lot of different hands in healthcare; it's a really complex space and there’s a lot at stake. I’m always mystified by how hard it is to align different parties’ incentives to result in the right outcome for patients. It underscores the importance of Alto’s mission: to fulfill medicine’s true purpose — to improve quality of life — for everyone who needs it.

Tell me a little bit about your current role. What are you most excited by? 

I’ve loved seeing how the different pieces of the company connect, and being able to connect the dots when we’re missing something. It’s been really fun to see how a little bit of communication and collaboration can go a long way. I also love thinking about how what we’re doing today could set us up for bigger things in the future, and how we build today in a way that opens a lot of doors for us down the line. 

In your opinion, what are the biggest opportunities for the company? 

There’s always an opportunity to be excellent at the basics. Are we consistently providing the best patient experience? Are we getting patients the best price? Are we saving time for prescribers and their offices? Those are problems that we’ve been solving for a long time, but it just gets more interesting and challenging as we’ve gone into new markets and therapeutic areas, and worked with different kinds of patients and prescribers than we used to. 

Something that I’ve always been intrigued by is - how do you bring more transparency around pricing to prescribers and patients at the earliest possible time, so that they can make the best decisions? It’s something that’s really missing in the industry. It’s not easy to do, and that’s definitely something I think a lot about - ‘How can we be the one who makes it easy for prescribers to know what they’re about to send to the patient, and for the patient to know what their other options are?’ Because a lot of times, what your insurance may cover and what your doctor may prescribe may not always be the best option. There might be other options, and I think a lot of people don’t know to ask about that. 

What are the biggest challenges in the pharmaceutical industry today? 

I think there’s been a lot of great activity from different patient advocacy groups and state governments to regulate the worst of what’s happened in healthcare. It’s been cool to see that take shape over the last five years. The challenge is that it’s very hard to write legislation and force some of these things, and so I’ve honestly gotten more interested in how do you write the right laws and approach regulation in a way that allows innovation to still happen and thrive, and still protects the patient at the end of the day. 

Back to your engineering roots – what advice do you have for young engineers?

Given the state of venture capital and the industry, a lot of engineers are going to earlier-stage companies, because there’s a little bit more investment and activity happening. I had to figure that out along the way - how do you operate as the third engineer on the team? Being anyone in an early-stage, small company - and an engineer especially - comes with its own unique challenges and skills. It’s not something there’s a ton of resources around. There’s a lot of resources about how to start a company, but not a lot for how engineers can grow their career at a company at that stage. So, my advice would be to seek out mentorship and cross functional peers from whom you can learn and grow. 

You pivoted from engineering to operations and strategy. What advice do you have for someone looking to make a career change? 

As an engineer, I’ve really focused on making an impact, whether that’s through building a product or shaping the business with what I know, with tech being the backbone. And I think that’s something we don’t talk about as much in engineering - how do you take your skills and really channel them for maximum impact and better understanding of a business? And for people who want to start their own companies someday, taking the path I did could be really valuable. It allows you to be a better entrepreneur and a better contributor if you can see the connection between engineering choices and the systems you’re building, and how they impact your customer and other parties. 

The other piece is being comfortable with wearing a lot of different hats. It’s what really helped my growth, and it’s counter to a lot of advice you get. People will tell you to go deep, get specialized and go down one path. You need to, to some extent; I absolutely had to figure out how to be a better engineer and a better leader. But the most growth for me wasn’t necessarily to stay in engineering – it was to take a turn. Hopefully, I can give colleagues a little more confidence who want to take a turn and increase their impact, growth and learning.

Staying on track with treatment and fully benefiting from a medication entails more than simply filling a prescription. It requires patients to take an active role in their health journeys, with education, clinical monitoring, and side effect management all necessary for proper drug utilization.

How Alto’s High-Touch Model Supports Patient Engagement

Pharmacists are an invaluable healthcare resource for those with complex treatment plans. Unfortunately, the traditional retail and mail-order models fail to maximize the possibilities of pharmacy care, without opportunities for ongoing engagement with patients. Not only are retail pharmacists often inundated with many tasks, it’s difficult for patients to discuss their health in a crowded store with a line of other customers behind them. And patients receiving their medication by mail often have limited visibility into delivery details or difficulty connecting with the pharmacy team. 

Alto Pharmacy offers a supported and convenient prescription journey at every step. We ensure that our patients have the information they need to get started with specialty medications and feel confident about their care. In addition to providing a simple onboarding experience, we have a team with robust clinical expertise and a high-touch model that allows patients to easily benefit from it.

We are also expanding our reach to fertility patients through our new nationwide* mail-order offering. Patients who receive fertility medications through mail-order experience the same convenience and support as those we serve via local courier delivery, with seamless onboarding, easy and supported medication management, and access to experts. 

And with an integrated and customizable tech stack — including both our proprietary pharmacy management software and our patient app — there are many ways for partners to provide additional engagement and supplement other support programs.

Here’s how Alto’s model enhances medication education and gives you, as a partner, the opportunity to more deeply engage our shared patients.

Alto offers a supportive and simple patient onboarding experience with proactive multichannel communication. We give patients a welcome text or call within 60 minutes of receiving their prescription, guiding them through their first order. Those who need to transfer an existing prescription to Alto can do so within minutes in our app.

If more information is necessary to fill a prescription, we make sure that patients and providers are both fully in the loop. We keep the patient informed at every step of the billing process, offering support with prior authorizations as needed. Through Alto Connect, our free communications portal for providers, clinical teams can view active medication details and quickly understand when additional steps are required to fill a prescription.

Partner Opportunities to Supplement Patient Support

The majority of Alto patients use our app for intake, medication ordering, and delivery scheduling. Not only does this give patients control and convenience in managing their prescriptions, it provides opportunities for additional engagement from partners.

Our flexible technology capabilities allow for many possibilities, including in-app introductions to your medications. In this video, a specialist from our fertility team walks patients through injecting the Gonal-f® RFF Redi-ject® Pen.

Follow-Up and Improving the Patient Experience

Easy onboarding is just the beginning. Alto supports patients at every stage of the prescription journey so that they can get the most benefit from their medication. Our dedicated medication therapy management pharmacists, who focus entirely on disease state education and support for chronic conditions, proactively contact patients who take specialty medications to review their regimens.

We ask if they are experiencing any side effects and track all patient-reported outcomes. As a partner, you can have access to data and insights into your patients’ experience of your medications.

We’re also able to tailor a patient’s treatment to any titration schedule prescribed by their provider. In these cases, we inform the patient of this schedule and change in medication dosage at every step of the treatment.

We see our NPS of 88 as an attestation of our patients’ love and commitment to both Alto and their health.

Tech-Based, High-Touch Patient Engagement at Alto

At Alto Pharmacy, a patient’s financial wellness is of the utmost importance. We understand that cost is one of the most common barriers to medication access, and we go above and beyond to connect patients with any savings opportunities that they may qualify for. 

Alto Pharmacy’s Product Controls for Coupons

At the same time, as a specialty pharmacy, we have a responsibility to protect the integrity of assistance programs and ensure that only eligible patients benefit from these resources. Our integrated technology stack provides the controls needed to restrict savings access to qualifying patients. Take a look.

The two components of Alto’s technology stack are both integral to our coupon controls.

Our proprietary pharmacy management software, Wunderbar — through which more than 80% of our prescriptions are automatically billed by algorithms — gives us both control and flexibility, with the ability to set custom workflows and requirements.

Our patient app — which the majority of Alto patients use for intake, medication ordering, and delivery scheduling — integrates with Wunderbar. With many areas for patient input, including coupon sign-ups, the app allows us to easily provide data to partners and further supports our controls.

Multiple guardrails for controlling coupon use

Our robust technology platform gives us multiple ways to ensure that coupons are applied to those who are eligible.

Providers often include ICD-10 diagnosis codes on prescriptions to aid in prior authorizations and coupon use. The provided information is entered into Wunderbar during our automated intake process. Our billing controls can limit coupon use to a specific diagnosis code if necessary, allowing for proper distribution of a medication. 

If a provider did not include the necessary diagnosis code for coupon verification, the patient can verify their diagnosis through the app. Our tech capabilities allow us to create pop-ups or notifications as needed for patient input. This patient attestation can be customized for different medication coupon scenarios and reported outcomes.

With a flexible tech stack, we can easily create additional workflows or automations to further regulate savings applications. These are some of the filters we can use:

Since we use proprietary software, we’re not only able to ensure appropriate application of savings opportunities — we have so much available data about coupon use to share with partners like you.

We can provide NDC and patient-level insights, including coupon application, the exact amount of money saved, and how many fills were delivered. These data insights could help develop market access strategies by monitoring gross to net gaps and identifying the opportunities for copay accumulators and maximizers.

At Alto Pharmacy, a patient’s financial wellness is of the utmost importance. We understand that cost is one of the most common barriers to medication access, and we go above and beyond to connect patients with any savings opportunities that they may qualify for. 

At the same time, as a specialty pharmacy, we have a responsibility to protect the integrity of assistance programs and ensure that only eligible patients benefit from these resources. Our integrated technology stack provides the controls needed to restrict savings access to qualifying patients. Take a look.

Pharmacists are one of the most accessible healthcare professionals, seeing people 5 to 8 times more frequently per year than primary care providers. Their role has become more expansive than ever, and many people don’t realize just how integral they are to a patient’s health and well-being.

National Pharmacists Month Spotlight: Travis Allison

At Alto, fulfillment pharmacists focus on dispensing medication — ensuring that the entire process is carefully monitored every step of the way — while patient advocacy pharmacists tackle anything related to a patient’s wellness, from provider communication and insurance coordination to guidance on managing chronic health conditions.

These specializations have opened up entirely new possibilities for the patient-pharmacist relationship at Alto. And this October, as we celebrate American Pharmacist Month, we’re spotlighting a few of the extraordinary Alto pharmacists who focus on patient advocacy.

To kick things off, we’re pleased to introduce Travis Allison, a patient care pharmacist based in Dallas, Texas.

What motivated you to pursue a career in pharmacy?

I took the long and winding road here. I didn’t always know this was what I wanted to do. In college, I started off as an English major but had a change of heart after a semester or two. I went on to study agriculture, and those experiences made me believe that I could pursue a path grounded in science.

My childhood memories of visiting the pharmacist were always in the back of my mind. As a kid, I hated going to the doctor. When those dreaded appointments were over and done with, I knew I’d get to see a guy in a white coat who would give me something to feel better. I always saw pharmacists as a comfort in the often scary world of healthcare.

What challenges have you encountered as a pharmacist?

At any chain pharmacy — which is where I spent my career before Alto — pharmacists are inundated with so many tasks. It isn’t that these tasks are unrelated to pharmacy, but they interfere with our ability to deliver patient care.

On a typical day, I would give 100 Covid shots and fill 200 prescriptions by myself while also coordinating billing and calling doctors’ offices. We also had to think about corporate metrics. I was frequently asked to get more people signed up for text message alerts and hit specific quotas.

Patient care is always the priority, for any pharmacist, but the reality of my job made it extremely difficult, and often impossible, to give patients the time they deserved.

The first thing I noticed when I started at Alto were the specializations. We have many different team members to handle all the responsibilities that fall on a single person’s shoulders at a traditional retail pharmacy.

I’m a patient care pharmacist, which is distinct from fulfillment pharmacists who process prescriptions.

I review prescriptions for accuracy and initiate medication transfers, and I interact with both patients and doctors. I’m here to answer any questions a patient has about their medication.

In a way, I feel like I’m on the frontlines the same way that I was when I worked in a pharmacy chain. It’s all of what I liked about retail pharmacy without the distractions of retail. We’re able to practice our most important functions as pharmacists without the noise.

We’re utilizing technology in a way no other pharmacy does, which allows us to communicate with patients and providers in so many different ways — without having to rush through interactions.

And the wheels of change turn much more quickly at a tech-oriented company than they do at a massive corporation. At my previous job, you could have conversations all day about what improvements were needed, but nothing ever happened. Alto was founded by software engineers, and we’re able to easily make changes in real time.

As a digital pharmacy, we serve so many patients that only we can serve. I talk to many who are homebound without a caretaker. Because of Alto’s model, I’m able to communicate with them, and we’re often their only point of contact within the healthcare system. I don’t know of another way these patients could get pharmacy care.

The digital model also allows us to get a broader view of healthcare, and to make an impact on a larger scale. Alto was one of few places where New Yorkers could get the Covid medication Paxlovid when it was first introduced.

It was incredible to be sitting here in Texas, getting prescriptions out in New York City just as a new variant came out that was really devastating to the city. At no other pharmacy would I have been able to help out my neighbors in New York.

Those moments where you can tell in a patient’s voice that you seriously helped them. To me, that’s an indication of how well I’m doing my job, much more so than the number of prescriptions processed or dollars generated.

When Jake Moffatt says he loves building things, he means it — sometimes literally. A construction project manager turned engineer, Jake has spent the past decade building software at mission-driven organizations. Today, as Engineering Manager of Alto Assistant, he leads the team that’s bringing wizard-like support to Alto’s customer-facing app.
Below, Jake chats with fellow engineering manager Mike Riess and recruiter Braden Hanlon about the work ahead for Alto Assistant.

I’d love to learn more about your background to get us started. How did you end up in software engineering?

When I was twelve, I started learning to code in QBASIC because I wanted to make video games. Once I wrote my first program, I was hooked! I loved computers and the creative power they gave to anyone willing to invest the time and energy to learn. Since then, I’ve built games, personal tools and projects, desktop software, and a number of apps and services — I love building things. My career has gone back and forth between construction and software engineering, but it’s been firmly in the software industry for the last ten years or so.

My favorite place to be in a company is working on something new that has a big impact or addresses an important problem. In a previous role, I built an app that helped people find roommates in a city where housing is prohibitively expensive. At that same company, I led the team responsible for creating a new vertical that eventually split off into its own company.

The goal of Alto Assistant is to help customers help themselves before reaching out to support. Our first project is introducing a wizard-like support “assistant” (hence the team name!) that guides the customer through a series of questions to narrow down the area of support. We’ve already identified a few tasks the assistant can help customers complete on their own, including making changes to upcoming deliveries or scheduling new orders.

In cases where we can’t help them just yet, our new tool generates data to help us to learn exactly what customers need help with. It’s a top priority to bake analytics into every new feature we build; even though we have years of experience supporting our customers — and we know intuitively which problems they frequently experience — we don’t have conclusive data to draw upon just yet.

We plan to start with a couple of frequent use cases and measure how often customers reach out to us for support. Then, we’ll chip away at the problem until we’ve seen a substantial improvement in the user experience. From there, we’ll move on to the next biggest problem and repeat the cycle. There’s a reason “Chip away it” is an Alto value: It’s the playbook that we’ve used to automate other critical parts of the pharmacy value stream like intake, billing, and fulfillment.

What opportunities are you most excited about?

Support drives much of the cost of every shipment today, so this is a high-impact area for our business. A year from now, it would be a stellar outcome if the Assistant team could reduce the number of issues that customers need support on by half.

We’re also thinking about the user experience beyond the app. We plan to improve the tooling that our care specialists use to provide support as well. We’ve already discussed some promising ideas like creating the concept of a conversation in support communications rather than an infinite stream of messages and building out enriched communications. We also intend to develop a custom tool that can expedite a customer’s prescription when they need their medication ASAP.

The possibilities are many, and it will take a team of determined, passionate, empathetic people to solve these challenging problems. I’m super excited to see what the Assistant team will do together.

Any lessons learned from previous experience that you’re applying to your role at Alto?

There’s always the temptation to tackle everything at once with new business initiatives. My experience leading new verticals at Apartment List and Snapdocs taught me the importance of being laser-focused on one or two key metrics instead of trying to build out a fully-realized product from the beginning. That’s exactly what we’re doing on the Alto Assistant Team with our clear focus on reducing communications per shipment — how often customers reach out for help because they could not find what they needed in our app.

It’s also important to recognize that we won’t have all the answers right out of the gate! I like to think of product development as a three-step sequence: learning, growth, and maintenance. Alto Assistant is so young that we’re very much still in the learning phase. We maintain a tight iteration loop with everything we ship: launch, measure the impact, and use the results to iterate and refine our hypotheses about what our users want. Our final product could be anything from a customer support wizard to an AI chatbot to a ticketing system — we have to rely on our key metric of communications per shipment, experimentation, and user feedback to shape the direction.

What got you excited to join Alto? What would you pass on to an engineer thinking about applying to the company?

I was impressed by the Altoids I met during the interview process. I knew I would be working with people from whom I could learn a lot, like Elnaz, who started as an individual contributor and went on to become Director of Engineering and, now, Alto’s first Head of Strategy & Operations. I was also impressed by the quality of the interview process itself — a good sign that the company was well-organized internally. Finally, the pitch for the role was extremely clear, with already-established key metrics that would directly contribute to the company’s bottom line and help Alto become more profitable.

For engineers, I think Alto is a great place for both technical challenges and career growth. We’re still small enough that every individual gets exposure to a broad portfolio of high-impact projects. It’s also a great environment for learning about how a business works — the Product & Technology organization does a great job of sharing information and presenting problems in a way that gets to the root business problem we’re trying to solve. There’s a clear line between any project a team is working on and a foundational business metric. Most importantly, we’re a company that makes a truly positive impact on our users’ lives.

Redux is great for managing client state: it allows data to be synchronized across the whole app, reduces prop drilling, and makes it easier to understand when state changes occur.

Server state is a different story. Sure, it’s nice to have data available everywhere in our app, which is why we tend to fetch data from the server and dump it into our Redux store. But because our client application doesn't own that server data, it’s hard to know when it has become stale. And what if multiple components trigger calls to fetch the same data? How do you dedupe requests? How do you decide when to refetch?

Why We Switched to React Query for Managing Server State

Redux is great for managing client state: it allows data to be synchronized across the whole app, reduces prop drilling, and makes it easier to understand when state changes occur.

Server state is a different story. Sure, it’s nice to have data available everywhere in our app, which is why we tend to fetch data from the server and dump it into our Redux store. But because our client application doesn't own that server data, it’s hard to know when it has become stale. And what if multiple components trigger calls to fetch the same data? How do you dedupe requests? How do you decide when to refetch?

Below, we’ll dive into how we’re using React Query at Alto to solve these problems and achieve separation of client and server state.

The Old Way: Fetch Server Data and Store It in State

Historically, we would fetch data and set the response in our React component state.

fetchUser(params) {
 this.setState({ isLoading: true });
 
 return getUser(params)
   .then(({ data }) => {
     this.setState({
       isLoading: false,
       user: data.user,
     });
   })
   .catch(() => {
     toaster.toast({ title: 'Something went wrong...' });
     this.setState({ isLoading: false });
   });
}

To make that data accessible from other components, we’d set that data in the global Redux store. This works fine, except that you have to manage your own loading state, the logic for when and when not to make the request, updating the store when mutating data on the server, and knowing when data is stale.

The React Query Way: Fetch and Cache Server Data

With React Query, fetching data and using that data is more declarative.

const { data, error, isLoading } = useQuery(
 // This is our Query Key, which is unique per query so that React
 // Query can manage the cache for us.
 ['user', { userId }],
 
 // This is our Query Function that actually does the data fetching.
 // We can use anything we want: built-in fetch, axios, etc.
 fetchUser({ userId }),
 
 // This query will not execute until the userId exists.
 { enabled: !!userId },
);

Here, we define our query for a user with a Query Key and a Query Function. The Query Key is unique per query, so React Query can manage our cache for us, and if any part of the Query Key changes, the query will automatically fetch new data. In this example, if the user ID changes, the query will fetch new data for that specific user and store that data in the cache.

Naming is hard, but caching is harder. React Query gives us caching of server data out of the box with cache invalidation and request deduping. If we use this same query with the same Query Key in another component, it'll check the cache: if the data is already there, React Query will simply return it, avoiding extra network requests!

Additionally, useQuery runs wherever you use it — no more fetching data when a component mounts. You just use the query and display the data when it’s ready. The cherry on top? The query returns status updates by default, so we don’t need to store isLoading in component state all the time.

Three Optimizations We Get With React Query

When we rebuilt Alto Connect, our web app for healthcare providers, we found impactful benefits in using React Query to help us manage server state instead of using Redux. Alto Connect provides instant access to patient and prescription information and enables messaging with the pharmacy. Because healthcare providers need to quickly switch between patients and clinics, caching data is important to provide a delightfully fast experience. Apart from the cache, what other optimizations do we get by using React Query? Below are a few that helped us.

Once we’ve queried for some data, it gets entered into our cache, so we can utilize that cached data when using the same query in a different component or when fetching new data for a stale query in the background.

React Query is configured with aggressive but sane defaults and considers cached data as stale. Stale queries will always query for new data when the following criteria are met:

The query is optionally configured with a refetch interval

The fetching for new data when the browser window or tab is refocused is especially useful because the healthcare providers using Alto Connect often switch between multiple browser tabs. If there’s an update to a task, status, or message while they’re checking a patient’s medical chart, it will be immediately reflected in the UI when they come back to Alto Connect.

We also set a refetch interval for our queries involving messages. In the old app, we used WebSockets to enable real-time messaging. Although it’s possible to integrate WebSockets with React Query, we opted for a polling solution instead. Because our app isn’t a real-time messaging application, and we don’t need messages to show up immediately, we set a refetch interval on our messages query to poll for new messages every 30 seconds.

const { data, error, isLoading } = useQuery(
 ['user', { userId }, 'messages'],
 fetchMessages({ userId }),
 {
   // This query is disabled from automatically running if we don’t have a userId
   enabled: !!userId,
 
   // Refetch every 30 seconds
   refetchInterval: 30000,
 
   // Continue to refetch while the tab/window is in the background
   refetchIntervalInBackground: true,
 },
);

This is where the enabled option, which disables a query when it evaluates to false, is particularly powerful. We can pause polling for messages if we route to another page and we know that we won’t make any unnecessary requests if there isn’t a valid userId. We don’t have to worry about closing any socket connections or manually clearing an interval.

Most web apps have some sort of navigation menu, and if you already measure or understand your user behavior, you can prefetch data before users even navigate to a different page. Custom hooks makes it easy to expose a function to prefetch data:

export const usePrefetchUsers = () => {
 const queryClient = useQueryClient();
 const prefetchUsers = async () => {
   await queryClient.prefetchQuery(
     ['users'],
     fetchUsers,
   );
 };
 
 return { prefetchUsers };
};

We prefetch queries when users mouseover or hover over a navigation item so that when they navigate to the next page, the data is either actively being fetched or is already in the cache waiting.

We’ve been talking a lot about queries, but what about mutating data? Mutations, in contrast to queries, are imperative. While queries run automatically when we use them, we need to fire a mutation method in order to run mutations. And in order for our user experience to feel snappy, we can optimistically update the cache and then invalidate it after successfully executing the mutation. useMutation gives us some nice side-effect handlers to deal with every stage of the mutation lifecycle. Now when the user sends a message, that new message is immediately reflected in the UI and we keep the data in sync by invalidating the cache and refetching the messages.

With Redux, we needed to build out solutions to each challenge of managing server state. React Query, on the other hand, gives us those tools right out of the box. We no longer need to worry about when to invalidate or fetch new data, making the user experience more predictable — and the developer experience more enjoyable.

Last summer, Moringa Fellows Irma Figueroa and Adrian Mendez joined Alto as the company’s second batch of engineering interns. Here, they share their learnings, accomplishments, and advice for future Alto interns.

Two Engineering Interns Weigh In: What to Expect From Your Alto Internship

The Moringa tree flourishes almost anywhere it’s planted. It’s hardy, fast-growing, and resistant to drought — an apt metaphor for the two interns who joined us from the Moringa Fellowship program last summer.

“Before Alto, I had never actually contributed to a large codebase,” admits Irma Figueroa, an intern on the Supply Chain Team. By the end of their three-month internships, however, Irma and fellow intern Adrian Mendez had shipped impactful features for Alto’s internal pharmacy management system and customer-facing app that are still in production today.

Below, we chat with Irma and Adrian to learn what it was like interning at Alto, which projects they worked on, and what advice they’d give to future interns. 

Adrian, who interned on the Patients Team before returning to join as a full-time software engineer last fall, was surprised by the freedom he had to choose what he worked on during his internship: “Early on, my manager gave me a rundown of the projects the team was juggling and the option to choose which one interested me the most,” he says. “I was able to decide the kind of experience I was going to have.” 

Adrian adds that meetings with his mentor evolved over the course of his internship, as he became more familiar with the codebase: “From the start, we had weekly meetings to talk about whatever was on my mind. Those meetings started off as general advice and questions and turned into more time to pair or run things by each other.”

Because both Adrian and his mentor were working on the same, long-term project, some of those meetings were also dedicated to project work. This included “sitting with [my mentor] while creating the project outline, pairing on larger tasks, and syncing up on progress.” 

Which projects did you work on during your internship? 

On the Supply Chain Team, Irma was tasked with a unique inventory challenge: Technicians at our production pharmacy locations use handheld scanners to scan the barcodes on newly-received inventory. Our technicians often need to scan hundreds of inventory items at a time — making it all too easy to lose track of which items have been successfully scanned onto which shelves. 

“I created a reusable counter component, displayed in the header of the scanner app, that would represent the number of items scanned into a shelf.” Irma says. The best part? Getting to test the handheld scanner herself. “I really enjoyed using the scanner for testing purposes. It was rewarding to see my code in action and definitely super fun!” 

On the Patients Team, Adrian worked on a project to add a homescreen to the customer-facing native app. Previously, the app dropped users into a list of all their active medications, which made it difficult to know where to look or what to do next. The new homescreen allows users to schedule the prescriptions most relevant to them and to view or edit any upcoming deliveries. 

“The first step was to create new additions to the design system — essentially taking the designs and extracting system-wide components. After that, the fun part was taking all those components and putting them together like building blocks!” Adrian says.

It was especially rewarding, he adds, to have been part of the project from start to finish. “I joined right as the design phase started, and I was there mostly every step of the way. For how short my time here was, having helped create this landmark project is really cool to think about.” 

What advice would you give to future Alto interns?

Irma and Adrian agree: Don’t be afraid to ask for help. “You'll often feel challenged and possibly intimidated, but be patient with yourself and remember you have an entire team of experienced engineers ready to help,” Irma says. 

“Everyone at Alto is more than willing to help you out, so don't be afraid to ask questions! You're on the same ship as everyone else, so your success equals everyone’s success,” Adrian adds. “Just remember that your work got you here, and they wouldn't have invited you if they thought you couldn't handle it. They made an investment in your ability to grow, so stay curious.”

With more engineers contributing to Alto’s codebase than ever before, we needed to establish better boundaries: which team owns what? Here’s how we developed a tagging-based solution to code ownership and drove and measured adoption.

How We Established Better Boundaries and Clearer Code Ownership at Alto

Some problems are nice to have. Over the course of 2020 the engineering team at Alto saw explosive growth, expanding from about fifteen to more than seventy individual contributors. Growth at this pace required us to rethink our team structures and priorities more than once. This growth felt amazing: the new capacity enabled us to make progress on our backlogs like never before.

But still, there were challenges. We saw a steady rise in merge conflicts as more people contributed to the same code base. Build times increased as more and more code was contributed. A big influx of new perspectives and talent also meant new gaps in historical context and responsibility. New teams took big bites out of their new priorities — great! But what about the old ones? Who was going to fix that bug? Who needs to review this PR? Who is accountable for this performance problem?

Who, in short, owned what? By the end of 2020, it was clear to us that a good, practical, working answer to this question would be the critical first step to continuing smooth, rapid, distributed iteration on our product.

Up to this point, the large majority of product development at Alto had happened in the context of a Ruby on Rails monolith, which — over a half decade of intense development — had grown pretty large. We’d stuck more or less to the default Rails convention of organizing code by function rather than feature, which meant that our code was distributed across a few mostly flat and very broad subdirectories such as '/models' and '/controllers', making it difficult to learn much about the structure and ownership of our business domains by merely looking at how the code was laid out. We knew that this was not going to work for us over the long term.

Our long term vision started to coalesce around a notion of “better boundaries.” First, we would modularize the monolith along the lines suggested by Shopify’s packwerk utility. Then, we would carve some of those modules out into separate engines that could be built and tested separately. Finally, we’d deploy and operate some of those engines independently as their own services. Clear ownership was fundamental to this plan: on either side of an effective boundary, you need to know not just what it is but also who owns it. We lacked that clarity.

The RFC (Request for Comments) we ultimately adopted opened with four questions:

How might we produce a domain model and do something useful at the same time?

How will we avoid imposing (the wrong) prescriptive model from the top down?

How will we keep it up to date and accurate?

We considered jumping straight into moving files around into a more modular structure. Ultimately we decided against this approach as a first step for a number of reasons. The benefit of moving files around is mostly abstract — it’s not immediately clear what to do with a better module structure. It’s relatively expensive to move files around in a Rails app — doing so typically requires you to rename the contents (and update all its callers), which amounts to a lot of busy work, and it’s extra expensive to be wrong. And the in-between state is rough: which example should I follow in deciding where to put my new file? First you are obligated to create a map of the future state, and then to keep that map in sync with reality as you go.

Instead, we opted for a lightweight solution that would allow us to map our domains and their owners in the code itself — helping to ensure it’s up to date and accurate — without having to restructure it at the same time. We’d do this by tagging code in code comments, and then building tools to leverage these tags in various ways to increase visibility and enforce ownership. This has the nice effect of producing a new domain map incrementally from the bottom up, rather than prescriptively from the top down.

We called this the '@owners' tag, and it looks like this:

# @owners { team: platform, domain: orders }
class Wunderbar::OrdersController < Wunderbar::WunderbarController
  def show
		...
  end

  # @owners { team: inventory }
  def out_of_stock
    ...
  end
end

We based our tooling around extending the YARD documentation tool to recognize this as a custom tag. You can teach YARD to recognize a custom tag by passing a command line option like '--tag owners:"Owners"', which by default will cause the tag value to appear in generated documentation under the header “Owners”. The Ruby API for declaring a tag programmatically is shown in the snippet below as well.

We wanted the tag to be interpreted hierarchically to handle cases where ownership has diverged within the same class or module, such that we might want to tag one or two methods differently from the rest, as well as to ease the burden when all of the classes / modules / methods under a namespace belong to the same team and domain, since you can just tag the shared parent. We set an initial goal around getting 100% of our methods covered by at least a “team” value, at which point we would require all code to be covered in our build process.

To get a basic feel for how to work with these tags, make sure the 'yard' gem is available, tag a couple of your files, and then try running the code below in your project. It will print out the tag associated with each tagged code block.

require 'yard'
# Define the custom tag.
YARD::Tags::Library.define_tag('Owners', :owners)

# Parse your codebase. You might want to pass a more specific path here.
YARD.parse('.')

# Load all the method, class and module code blocks into memory
code_blocks = YARD::Registry.all(:method, :class, :module)

# Print the tag associated with each tagged block.
code_blocks.each do |code_block|
  tag = code_block.tag('owners')
  # automatically tag nested classes, modules and methods.
  while tag.nil? && code_block.namespace != nil && [:class, :module].include?(code_block.namespace.type)
    code_block = code_block.namespace
    tag = code_block.tag('owners')
  end
  print "Code Block: #{code_block}, tag: #{tag.text}, line: #{tag.line}" if tag
end

We ultimately developed a handful of CLI tools based on this technique that allow us to produce reports measuring the percentage of code covered by team and domain at different levels, among other things:

bin/yardowners --help
Usage: bin/yardowners [options]
        --methods                    view by methods
        --files                      view by files
        --teams                      teams report
        --domains                    domains repot
        --team=TEAM                  filter by team
        --domain=DOMAIN              filter by domain
        --codeowners                 update codeowners
        --lint                       lint owners tags
        --require-domains            lint for presence of domain in  
owners tags
    -h, --help                       display this help and exit

We use this CLI to add checks to our CI process around coverage / correctness, as well as to report progress toward our goals of 100% coverage.

To get the tagging process started across the organization, we dumped all of our class and module names (thanks again, YARD!) into a big spreadsheet, and then asked each team to get together and spend a bit of time putting their names next to the ones they owned. We adopted the attitude that it was better to have the wrong value than no value, since it would be easy to adjust later.

We covered a good 80% of the code using this spreadsheet by the time each team had taken an initial pass. From there, we filled the blanks in with “TODO”, and then wrote a little script to automatically insert the tags into the code (again based on the YARD metadata, which conveniently gives you the line numbers for the top of each class / module declaration).

At that point, we enabled a linter requiring 100% team owner coverage on all new PRs. We set a new goal to eliminate TODOs, and chipped away at it over the course of a month or so. We then repeated this process for the “domain” values, driving that to 100% as well. We found that the spreadsheet-based divide-and-conquer approach allowed us to cover a lot of ground very quickly.

Once we were able to parse our '@owners' tags, the first and most important thing we did with them was to automatically generate our CODEOWNERS file. We enforce that each tagged team maps to a team name in github and check that CODEOWNERS is up to date during the build process. This new process introduced some friction, as teams started getting tagged every time a file they were tagged on changed. This turned out to be great, because it sparked a number of very productive negotiations around ownership and scope that got hashed out in code review. We keep our CODEOWNERS file synced with Sentry, too, so that exceptions raised by files you tagged as yours get assigned to your team automatically. We also track and report on the performance of individual endpoints by team according to how they are tagged.

The new owners tag hasn’t fixed all our problems by any means, but it has proved fundamental to our ability to operate as a growing set of increasingly independent teams with well specified responsibilities. In subsequent posts, we’ll talk more about how we’re using our new domain map and a suite of other cool tools to build better boundaries within and ultimately escape from our monolith.

To automate a manual, error-prone pharmacy workflow, we turned to event streaming. Here’s what we learned from one of the first Kafka use cases at Alto.

How We Used Kafka to Build an Event-Driven Automation Pipeline and Scale Our Pharmacy

Imagine this: You're at the doctor’s office, and your doctor just wrote you a new prescription. Minutes later, before you even check out with the receptionist, you already have a notification from Alto Pharmacy on your phone that your prescription is ready. All you have to do is pick the date and time that works best for your free courier delivery.

This is the future we’re building at Alto: a future where a prescription can be transcribed, billed, and verified by a pharmacist in five minutes, flat. To get there without dramatically increasing Alto’s head count, we need to automate much of the process, starting with the first step: transcribing, or intaking, a prescription.

As a pharmacy, we receive prescriptions in many different forms. Some are sent electronically, in a structured format, but others are handwritten, phoned in, or even faxed. To represent all of these forms in a single table, we previously required every incoming prescription to be transcribed by an Alto team member, who would answer questions like:

Whom is this prescription for? Is this customer already in our system?

Where did this prescription come from? Who wrote it?

What is the relevant prescription information (medication to dispense, quantity, days supply, directions, etc.)?

This manual process is both time-consuming and prone to human error, which, if uncaught, could impact our ability to process the prescription downstream. Furthermore, at our busiest times, it could take up to two hours for a team member to get through the pending intake queue — unacceptable if we hope to have prescriptions ready to schedule before people even leave their doctor’s office. 

Automating intake required close collaboration between three teams:

Data Science, who built the decision-making algorithms 

Data Engineering, who served up the results of those algorithms

Product Engineering, who used those results to automatically intake prescriptions 

To allow the teams to operate in parallel without toe-stepping — and in the language most suitable for each (the Data Science and Data teams prefer Python, while product engineers work mainly in Ruby) — we separated the code into two environments: 

1. Data Prod Interface (DPI), where the code for generating automation results lives
