At Spread Tecnologia, I developed digital banking products including a Digital Wallet, PIX, and Credit Cards for millions of users. I also developed a front-end library that served as an API contract for dynamic screen and form generation, eliminating routing bugs and cross-module dependencies.
At Digio, I transformed a Flutter Web monolith into a modular, testable system and helped raise test coverage from zero to over 70% through TDD adoption. Across my mobile development work, I’ve built Flutter and Kotlin apps, including an offline-first field-service solution that eliminated data loss and delivered R$ 300K+ in annual savings.
