about --bio

cat /home/rthiesen/bio.txt

I'm a software engineer from Brazil 🇧🇷. Enthusiast of all things that come together as a system. Love to hack, learn new tools, always eager to dive straight into learning by experimentation. I'm into software architecture, cloud deployments and mobile development.

Currently, I'm working at Grupo Panvel, where I develop awesome features for the Panvel app. My tech stack revolves around React Native, Java (Spring), and NodeJS, and I frequently deal with AWS and Azure cloud environments.

I'm always looking for ways to enhance my workflow by integrating AI-powered tools into my development process. I value practical, efficient, and maintainable solutions.

Outside of work, I enjoy RPG games, anime, and spending quality time with my family. I've been gaming since childhood — in fact, over 20 years ago I was already exploring the famous MMORPG Tibia! Nowadays, I mostly play World of Warcraft and competitive games like Valorant.
