Behind the Terminal

My journey into software engineering began at 42 São Paulo, a disruptive coding school that emphasizes peer-to-peer learning and real-world projects. There, I learnt not only to write clean, efficient code but also the importance of collaboration and continuous learning in tech.

Based in São Paulo, I've spent the last few years bridging the gap between complex technical challenges and user-centric product needs. Whether it's desiging small web applications or large-scale distributed applications, I focus on building systems that are resilient by default.

In my spare time, you can find me playing some Bossa Nova, listening to Brazilian Rap or on the beach with my wife and our 🐩 dog.
