What I'm looking for

I'm looking to build user-facing Android, iOS, and web products where I can own features end to end, solve complex workflows, and collaborate closely with product, design, backend, and engineering teams.

I've shipped and maintained five Flutter applications for Android and iOS at Megaleios, delivering authentication, onboarding, dashboards, maps, payments, registration, data visualization, and user-management experiences.

At Rav Tecnologia, I built Flutter and web interfaces for IoT, industrial, agricultural, and field-service systems. I improved automated test coverage by approximately 50% and reduced screen loading times by up to 90% through frontend, API, and data-loading optimizations.

I've also developed React Native applications at Polibras Software and DataSquads, improving product-listing performance by approximately 20% and refining benefits workflows, navigation, filtering, loading states, and API integrations.

I translate complex operational workflows into responsive, reliable interfaces, owning features from requirements and implementation through testing, release, and production improvement.
