A short
letter.
The studio is one person. I design, engineer and polish digital products for people and companies who understand that how a thing feels is part of how it works.
I have been building software for well over a decade. cbrl was established in December 2020, in São Paulo, as the formal shape of that practice — a company I could use to take work seriously. The intent has always been the same: software that reads as a single considered object, not a committee's compromise.
What shapes the studio today is AI. The studio is designed around it — prototyping, copy, variations, review, tooling. The tool multiplies the thought at every step; the operator decides what ships. Not a shortcut to mediocrity, but the only honest way for one mind to hold the whole product without giving up on the detail.
The focus is on SaaS — building my own products, looking for the one that earns its audience. Alongside that, I take on selected custom engagements for startups, companies, agencies and the occasional individual — whenever the problem is sharp enough to deserve the full treatment.

The specifics.
Multi-stack by principle. Years of hands-on experience across JavaScript, TypeScript, Swift, Python, Dart, Ruby and Go — with AI as a force-multiplier across all of them. The tooling adapts to the problem, not the other way around.

How the work happens.
- 01
Start with the shape of the problem.
I spend time with the domain until the problem statement is sharp. A clear brief is the shortest path to a product that deserves to exist; a fuzzy one guarantees rework no matter how fast the tooling is.
- 02
Prototype in the medium, with AI in the loop.
I design in code, not in static screens, and I use AI as a drafting partner — for copy, for components, for the ten variations I would otherwise never have time to explore. The decisions about what ships stay with me.
- 03
Polish until the last ten percent is the work.
The last ten percent is where a product earns trust — the empty states, the motion, the error copy. I plan for it explicitly and treat it as the work, not as a decoration applied at the end.
If the above reads like how you want your next chapter built, I would like to hear from you.
