About

I'm a senior engineer based in Brazil (remote), focused on shipping polished mobile and web products. Over 7+ years I've taken apps from Figma designs all the way to the App Store and Play Store — including authentication, subscriptions, CI/CD, and back-end integrations.

Most of my work has been with US and European teams through Toptal, across dating, healthcare, travel, and consumer apps. I care about clean architecture, reliable releases, and interfaces that feel effortless.
