What I'm looking for

I'm looking to build reliable web and mobile products end to end, working with cross-functional teams on complex requirements, scalable architecture, and production-quality delivery.

At Stefanini, I build production React and TypeScript applications for a critical international enterprise initiative, owning features through analysis, implementation, testing, integration, debugging, code review, and production support.

I've also stabilized and helped release a citizen-facing Municipality of Belo Horizonte application using Flutter, PHP/Laravel, PostgreSQL, and APIs. Previously, I engineered features for TK Elevator's flagship technician mobile app and shipped features across multiple Xamarin and Flutter applications at Dragon VC.

As an independent consultant, I've spent 8+ years delivering web and mobile products end to end. I built Ótica Integrada, a Laravel and MySQL retail-management platform that generated $800K in client revenue in FY2023, and I published the Pro-Mama maternal health app for Android and iOS.
