Summary
🤩
Rockstar🎓
Top SchoolPaulo Faria is a founding engineer and open-source leader with 12+ years building full-stack and mobile systems, specializing in Swift server and concurrent programming. He founded Zewo and GraphQLSwift, contributed core execution and parser logic to a Swift GraphQL implementation, and implemented concurrency primitives like failable channels for Venice—work that earned him visibility at WWDC. At startups and healthcare platforms he has driven architecture modernizations (MVVM, SwiftUI, modularization) and production-grade server and app features. Based in Paraná, Brazil, he combines a hacker’s creativity—his first project repurposed a fighting-game engine into a skateboarding game—with formal study in computational biology at Stanford, bringing both experimental curiosity and rigorous engineering to complex systems.
