About me

A bit of my journey

I'm Júlio César, a certified IT Technician from IFRO - Ariquemes Campus, currently pursuing a degree in Systems Analysis & Development (ADS). I discovered my passion for technology and programming early on, which led me to a 2nd place nationally at USP's Fase Zero competition among high school teams.

I currently lead mobile development at the startup Class-Up, building an app with Flutter/Dart. In parallel, I conduct research on 3D reconstruction comparing NeRF and 3D Gaussian Splatting. I also have experience with networking, AWS, Linux servers and Arduino/IoT.

I had the opportunity to be an exchange student through the International STEM Mobility Program in Costa Rica, and to take part in the Brazilian Robotics Olympiad (OBR).
