About

I lead by making the hard calls visible: what we build first, what we cut,
and why.

01

Systems, not one-off screens

Co-created Qu's first Global Design System, adopted by Enterprise Intelligence, Notify and Qu Order Management, and built Volt at EOS.

02

Close to the people on the floor

I start with operators, support teams and enterprise customers before I open Figma.

03

Scoped with engineering, not handed to them

Hard constraints like offline mode, legacy data and rush hour speed shape the design from day one. Lately I prototype straight from PRDs with Claude.
Portrait of Joao Medeiros

Before product design, I spent years in branding and signage in Brazil and the US, and before that I studied civil engineering.
I still work like both: structure first, then craft, and when it fits, a little joy.
