I'm a product engineer who has spent 10+ years building interfaces for systems where mistakes are expensive — Pix at Bradesco, international FX at Santander and the nationwide point-of-sale at Casas Bahia.

I studied architecture and service design, and it shapes how I work: thinking about the product end to end, from a Figma prototype to a production deploy.

What interests me is the moment a user hesitates — and what the interface can do so they don’t have to.
