Available to hire
I’m a senior mobile developer based in Salvador, Brazil, with 7+ years of experience building high-performance Flutter apps and mobile-first architectures. I’m a Flutter specialist since 2019 and I focus on clean architecture, scalability, and maintainable code, with a strong background in e-commerce workflows (cart, checkout, payments, login/account management, and personalized promotions).
I’ve delivered and scaled mobile products for major retail clients and popular consumer apps, integrating payment flows, analytics/crash reporting, remote configuration, push notifications, and REST/GraphQL backends. I enjoy collaborating in agile squads and I bring a strong engineering mindset—performance optimization, reusable UI components, and production-ready infrastructure—across Flutter, Dart, backend services, and cloud data tooling.
