For your app or for your site, from diagnosis to the deed: first I learn what really hurts, then map the flows you need, I draw the interface in full and hand the system to proceed.

Mercadin: shopping list
Product · UX/UI · 2026
A shopping list for iOS, designed so my mother can make the list and finish the trip with no one beside her. The core flow is already used at home. Data, accessibility and a whole trip without help are still under review.
Worten: Header + Menu
Design UX/UI · 2024
Mobile navigation redesign for one of Portugal's largest electronics retailers. Moving the menu away from the bottom of the screen and bringing services into view made an offer that already existed easier to find and use.
Worten — Action Button PDP
Design UX/UI · 2025
The product page's action buttons sat in the buying box, competing with price and the buy button. Moving favorite, compare and share into the gallery, where they stay in view on mobile, was a call about hierarchy.
e rural
Product Design · E-commerce · 2019
A livestock marketplace: price per animal, card instalments, freight with a window — and negotiation kept right beside the buy button. The platform still runs at erural.net.
Cosmos
Design UX/UI · 2021
Email, WhatsApp, Telegram, SMS and Widget in a single support inbox. The channel becomes conversation metadata, the bot answers to a dashboard, and the product still lives in the client's catalogue.
Lorni
Design UX/UI · 2021
School software for public schools in a continent-sized country. The lesson comes down to the device and works with no network, and every test is drawn from a bank so no two students get the same one.
Tapp
Design UX/UI · 2022
A travel guide that changes the filter: sustainability and inclusivity instead of price and stars, with the itinerary built by the traveller. UX/UI postgraduate project, done in a team.
Knowbie
Design UX/UI · 2021
A platform where e-Sports streamers sell playing hours. The product question was not how to charge, it was what exactly is for sale. The answer organized the whole app.

I was always drawn to German design. The Bauhaus: the bent tubular chair with nothing to spare, the typeface drawn with ruler and compass, the form that never apologizes. I am pixel perfect by nature, so it pulled at me — I wanted to be Jony Ive. Except the people I admire are not the ones who followed a standard, they are the ones who built a path of their own.
And none of them ever walked the dunes of Caueira, in Sergipe. When I looked around, nothing near me had that order. Too much color, too much material, too much pattern. A cauldron. It took me a while to understand the cauldron had a name, and the name was Brazil.
Here we do not have the rigor of process. We have the force to make it happen. While someone weighs the best way to act, we already did it, already got it wrong, and are already on the second version. I only understood the worth of that once I left. I spent four years in Portugal, designing the Portuguese government's vehicle registration system and product for Worten. I delivered all of it — flawless grid, every component in place, nothing off-pattern. And it was correct the way anyone's work would be correct: I could not see myself in it as the author of that work, as a creative. It was from far away that I saw it up close. The people I took as my ruler waited for the perfect tool to begin. The Brazilian starts with the tool at hand. Imperfection is not a flaw, it is proof that someone was there. Error is not failure, it is research happening.
I needed to build my own. Casebre is the record of that process — a revisit to my fascination with the Bauhaus, now run through the materiality and the culture of this place. Not the Bauhaus of the manuals: the Bauhaus of the working-class house. The Brazilian working-class house is the casebre, and that is where the flourish stops being ornament and becomes identity. A table with a plain white cotton cloth will never warm the heart the way the one with flowers in questionable colors does. The first is correct. The second is human — it has the warm hug the first one does not know how to give.
With clients it is the same move. I bring the pixel perfect I learned to love and let it live with the raw material, the color out of place, the workaround that solves. I accept getting it wrong in order to find out, and I build what reflects us. In the end it was never about choosing a side. It is the balance between the rigor that refines and the workaround that creates. Casebre is that house.
