With 20 years of experience building digital products, I'm a designer who codes and speaks the language of business. I'm a Brazilian living in Italy with my family, focused on bridging the gap between design and AI technology.

I've tripled MRR in 2 years at yampa, led a redesign that drove 4M+ downloads at Astrolink, and spent two decades shipping SaaS products that actually work.

Research revealed four critical friction points that reshaped everything — from trust barriers to onboarding failure. What followed turned a desktop-only platform into Brazil's category leader in astrology.

Two years cancelled. Rebuilt in two months.

A complete redesign cancelled a week before launch due to critical technical debt. The forced pivot became an AI-first workflow that rebuilt the entire frontend in under two months.

About

Cahê — between a pool lane and a whiteboard

I'm a Brazilian designer living in Ivrea, Italy — the city where Olivetti invented the personal computer — with my wife and two kids.

I've spent 20 years designing digital products. But before I was a designer, I was a developer — I have a technical background in programming and wrote code before I wrote specs. With AI, that side came back strong: today I deliver design and code in the same workflow, and it completely changed how fast I can ship.


Today I use Claude, Cursor, and Antigravity to go from concept to shipped product — sometimes in the same day. It's not a new trick: it's an old background meeting new tools.

Outside of work, I went back to competitive swimming with a masters team — after 22 years away from competition. It wasn't an easy decision. It's been one of the most intense things I've done, and a reminder of how much I love the sport.

I train at night, after the day is done. My kids compete too. There's something about that combination — father and kids in the same pool, racing the clock, trying to get faster — that says more about what drives me than any job description ever could.

That resilience of coming back after so long, not knowing if the body still remembers, with no guarantee of result — it shows up in my work too. And it's feeding a new project I'm not ready to announce yet.
