Based in Brazil · Working fully remote

Discovery-driven design, systems, and six years of shipping.

I'm Matheus, Matt if you prefer, a Product Designer working across fintech, B2B and B2C products for international markets. I run discovery end to end and carry it through to the interface, the design system, and the handoff that makes it real.
