Backend & distributed-systems engineer. Self-taught from Rio de Janeiro, shipping in production since 2017.
I started writing code as a young teenager in Rio de Janeiro, entirely self-taught, because I wanted to build things people would actually use.
What started as a Minecraft server I ran as a teenager grew into open-source projects, freelance work, and then production systems at real companies. The throughline never changed. I build things that hold up under real load.
Picked up programming on my own as a teenager in Rio de Janeiro. No course and no mentor at first, just a stubborn need to build things and watch them run.
Built and ran RedeLegit, my own Minecraft server. My first real product: I shipped the features, kept it online, and learned fast because players noticed the second anything broke.
Got paid to build plugins and systems for other server owners. My first taste of shipping to someone else's spec, hitting a deadline, and supporting what I delivered.
Turned the craft into open source the whole community could build on: 70+ repositories running across 1,200 servers and 15,000+ players.
The teenage hobby became a profession. I started getting hired to build production backends under real load, and carried over every habit I'd learned shipping in the open.
Started a CS degree at Inteli on a Telles Foundation scholarship. Since then I've led 10+ projects there as tech lead and begun teaching DSA and system design to a cohort of 12 students. Self-taught, now teaching.
Still shipping side projects on my own domains: AlgoViz, AdaLove 2.0, a YouTube backlog kanban, and credit infrastructure for micro-entrepreneurs.
Now I want to grow internationally through exchange and research, and to learn from engineers who push me further than I could go on my own.
