Brazilian in Portugal 🇧🇷🇵🇹
15 years as a dev. Now I build and operate my own SaaS.


Before becoming a dev, I worked with photography, video and design, producing for bands, at agencies and on my own projects. I've been a founder, then a dev at companies like Hotmart and Grupo Boticário, and each of those chapters feeds what I build today.
In 2024 I moved from Brazil to Portugal and went back to being a founder, now with my own products.
Today I run the SaaS I build myself, share real numbers on YouTube and help other devs do the same.
I don't sell magic formulas. I show the game as it is and build products in public.
Direct mentoring for devs and founders who need direction, not more theory.
