About

Developer with a founder's mindset

I'm a full-stack developer from Brazil who doesn't just write code β€” I build businesses with it.

I started in QA, got promoted to developer within 3 months for solving problems nobody else would touch, then spent 2+ years building web systems for organizations including international teams. In 2024, I founded a digital agency and scaled it from zero to over $20,000/month without any external investment β€” designing the operations, automations, and growth strategies from scratch.

Now I'm channeling all of that β€” technical skills, business instincts, and a bias for action β€” into building software that matters. I'm passionate about motorcycles, always chasing the next challenge, and open to remote opportunities worldwide.
