About Me

I was born in Brazil in 2002, and I’ve been keeping things moving since then. I’m a fan of hardware emulation and Linux, especially for retro video-game consoles. I started programming as a teenager, developing game engines at a time when engines weren’t as accessible as they are today. Today, I work as a software developer focused on modern Web Backend development with over 3 years of experience.
