I started my career in open source, as an intern at Conectiva, a Linux distribution from Brazil. There I went from programmer to team lead and architect, and got my first taste of leading people. I also worked on embedded Linux, in the days when phones had keyboards and the iPhone didn’t exist yet.
Then the iPhone arrived, and every phone with a keyboard suddenly looked old. I moved to the Nokia Institute of Technology in Brazil, where we worked on modernizing Nokia’s phones with Qt and Python. I spent a lot of that time in WebKit, back when Google, Apple, and Nokia all shared the same web engine.
I joined Red Hat in 2011 as a first-time manager, with a small team working on the KVM virtualization stack. KVM was still an emerging technology then. Systems software is where I feel at home, and it was a lot of fun to manage engineers working at the frontier of a technology that now runs under much of the public cloud. I stayed for a little over ten years, and by the time I left in 2022 I was running an organization of about fifty people on four continents.
At AWS, I was responsible for the core of Amazon Linux, the operating system on several million hosts across Amazon and AWS. I like to say it’s one of the most widely deployed operating systems that few people have ever heard of. AWS taught me what it means to work at that scale, where a small mistake can reach millions of machines.
In 2025 I came back to Red Hat, which brings me to Azure Red Hat OpenShift (ARO). Microsoft offers it as part of Azure in more than 60 regions, and our two companies build and operate it together.
When the current generation of AI tools showed up, I fell in love with them. They brought back the fun of building things, which I’d assumed was mostly behind me, and they’re changing how efficiently a whole engineering team can work. The technology itself is fascinating too, and I’m having a great time learning how it works under the hood.
I’m from Brazil, and Portuguese is my first language. English is my working one. I have a BSc in Computer Science from the Universidade Federal do Paraná and an MBA from Fundação Getulio Vargas, and I was the first in my family to go to college. I moved to the United States in 2018, and I live near Boston with my wife and daughter.
Outside of work and technology, I love science, travel, and time in nature. Lately I’ve been reading philosophy of mind and neuroscience, and my hobby project is a book on those subjects. I hope it sees the light of day before long.
