What I'm looking for

I’m looking for a software engineering role where I can build React Native frontend experiences with strong accessibility, scalable design systems, and clean architecture—while collaborating with teams that value quality (unit tests) and use AI to improve productivity.

I am a Software Engineer, graduated from the University of Brasília (UnB), and I hold a certificate in Distributed Software Architecture from PUC Minas. I have been working in the technology industry since 2020, with most of my career focused on frontend development—especially mobile experiences with React Native.

In my roles, I have built and evolved accessible, secure solutions for large-scale products, using Design System patterns and writing unit tests to keep quality high. I’ve also worked on backend systems using Node.js and .NET, implemented Native Modules for Android and iOS, and contributed directly to a mobile application rebranding by collaborating on new architecture and project standards. Recently, I’ve extensively used AI agents daily to boost development productivity, code reviews, and problem-solving.
