// ABOUT

André Daniel

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.
