With 20 years of experience, I've joined companies before the structure existed and left with something that lasts. I'm a designer who codes, speaks the language of business, and bridges the gap between design and AI technology.

I've tripled MRR at yampa by restructuring a product and its business model from the ground up. Led the redesign that drove 4M+ downloads at Astrolink. Two decades shipping SaaS products that outlast my time there.

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 who traded the city of the sandwich for the city of the orange battle. From Bauru to Ivrea — where Olivetti invented the personal computer — living here 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.
