Currently: Building at Netflix

I've been working at Netflix since 2020. It has been quite a ride.

Ecosystem Platform and Reliability • 2023 → Present

I'm a Senior Software Engineer on the Ecosystems Platform and Reliability team in Amsterdam—founding member and the only EPR engineer here.

We're part of Partner Experiences, which brings Netflix to as many devices as possible. The EPR team builds the platform that powers smooth integrations with partner devices across different verticals.

What I do:

My main focus is supporting Partner Engineers in Amsterdam during device certification and validation. When platform services act up, I help unblock them quickly.

I've focused heavily on reliability across the organization: data integrity, status pages, metric collection, alerting, database tuning, incident management, triage, remediation, post-mortems, on-call rotations, runbooks, software ownership, and vulnerability management.

When reliability was quieter, I worked on a centralized data platform that served us well for a few years, but eventually got deprioritized and we had to shift gears as a team.

After that, we shifted to working exclusively on our hybrid authorization layer called Protectorate.

I wrote load testing scripts to ensure Protectorate could handle huge volumes of grant checks, and eventually I was involved in a total revamp of our User Access authorization UI module—one of the most critical parts of the system, responsible for controlling role access for every workspace available to Partners enrolling Netflix into their devices.

Studio Tech Solutions • 2020 → 2023

Almost 3 years on the Studio Tech Solutions team—my longest tenure. I was the founding and only Amsterdam-based member of STS.

Building Genesis

I built Genesis: a semantic data layer that powers operational reporting for Netflix Studios. It supports 600+ reports used by thousands of people during content creation.

I started Genesis as a CLI in 2020 when we were struggling with report management and facing a major migration. The semantic layer let us create and migrate reports faster and more confidently.

We've since navigated multiple migrations—scheduling platforms, CLI tooling, schema changes, data source replacements—and the semantic layer helps us keep pace with a fast-changing data ecosystem.

Genesis is now owned by the Operational Data Infrastructure team, who continue improving it across data availability, UX, features, and maintenance.

Oh, and I won a hackday in March 2022. That was fun!

I worked solo from my home office or the Amsterdam office, since the STS team is based in the US.

Framer

One of the nicest jobs I've ever had. Loved the product, loved the people.

I spent 4 months at Framer, working on bug fixes, features, and performance improvements for Framer Web.

Highlights:

  • Migrated Framer Web to a new static assets service (replacing the Node filesystem) with zero customer impact
  • Discovered a critical RCE vulnerability in Framer Web: Webpack Inline Loaders could be exploited through the built-in code editor
  • Drove awareness and prioritization to get it fixed by the Build Server team

I loved the product and the people. Learned a lot in 4 months—would have learned even more with a few more years.

Travix: The Life-Changing Move

This job changed my life as a whole, and as a bonus, I've met some of my best friends here.

In 2018, I relocated from Vila Velha :flag-br: to Amsterdam :flag-nl: to join Travix. Almost 2 years there (02/2018 → 10/2019), working across multiple teams on their 5 main websites.

The Journey:

Backoffice Team — Worked with flight global distribution systems, ensuring our systems fulfilled flight ticket orders reliably.

Payments Team — Built the first UI team from scratch. We implemented alternative payment methods (Klarna, Sofort, Google Pay, Apple Pay), adapted the UI to async payment flows, and ran many A/B tests.

Experimentation Team — Joined a greenfield team building foundation services for server-side experimentation and A/B feature bucketing. This enabled backend teams to run complete server-side experiments without UI engineers.

Beyond the day job:

I built internal tooling for developers, including a Release Management app that became the de facto release notification tool, plus utilities for dealing with flaky end-to-end pipelines.

Before Amsterdam

Before all that, I worked across different industries in Brazil: Healthcare, ECommerce, Administration, Water Management, Forest Management, POS systems, and Open Source.

Most of this was contract work through software houses. I did plenty of backend work in Java and .NET.

Fluxor

I co-founded and ran Fluxor, a small software consultancy, for ~1.5 years with Guilherme Kammsetzer and Breno Poloni. We focused on ecommerce work, with High Company—a well-established global street-wear company based in Vitoria—as our major client.

What People Say

I've been lucky to work with amazing people who set the bar high and made me want to reach it. Here's what some of them have to say:

Armando is simply brilliant. A legitimate case of someone who was born to do what he does, Armando is a professional who breathes and lives the universe of development, he is an extremely qualified professional with whom I had the pleasure of working together.

I strongly recommend Armando because I really believe that there are few people with his skill, ability and potential, he has also strong qualities in communication, development of ideas and teamwork. I'm sure he's able to add wherever he is, even in the most difficult projects and challenges. Hope we can meet professionally in the future again

Breno Poloni

eCommerce Performance Analyst

Armando is one of the most passionate developers I've ever met. He is always digging in new trends, providing insightful comments and innovative solutions to the daily challenges one encounters in development. He's the kind of developer that, whenever he encounters a problem, he builds a solution instead of complaining about it.

Enrique Ramírez Vélez

Senior Frontend Developer

Armando is very good in explaining technical details in simple words, in a way that even a baby can understand how it works! It's usually possible only if the person understands the topic very deeply. He's a passionate engineer constantly expanding the range of his expertise and ready to help you anytime, which makes him a perfect team player.

Yuri Drabik

Solutions Architect

I have never seen a person with such a huge interest in IT like Armando. Having a can-do mentality, Armando proactively takes a lot of responsibilities, solves many complicated challenges, helps his colleagues and fully enjoys the entire process at the same time. If you need some boost of motivation - Armando can explain things with energy, joy & excitement like no other. This is what you call high IQ and high EQ combination in action! I'm totally recommending Armando as a great developer, leader, mentor and team-player! 👏

Jevgeni Rumjantsev

Senior Software Engineer

Armando is fearless while developing web applications. He can easily navigate from Front End to designing APIs, optimizing the CI, and back to Front End by the end of the week. His name was always appearing on the company monthly event either by delivering amazing features or by coding scripts or tools that helped the whole engineering team. He is a great team player and I definitely recommend his work.
