01 · About

Building digital experiences that hold up.

I'm a Brazilian Canadian engineer in Seattle with 8+ years turning complex problems into fast, accessible interfaces. At Amazon I lead frontend for internal HR and compensation platforms, own an organization-wide design system library, and pioneer AI-enhanced engineering practices across my team.

My focus is the unglamorous stuff that makes products feel effortless: performance budgets, component architecture, and accessibility done right. Outside of work you'll find me gaming, exploring new places, or attempting to cook (emphasis on attempting).
