About
I'm a software developer, AI expert, and designer with 10 years of experience building products from the ground up. My work spans full-stack engineering, LLM integration, and interface design. I care deeply about the space where code, intelligence, and craft meet.
Based in São Paulo, I've worked with startups and scale-ups across Brazil and internationally, leading both technical and design decisions. I believe the best software feels inevitable, technically sound, intelligently designed, and deeply human.
