• Led migration of a live betting app to a modular Flutter monorepo (Clean Architecture, BLoC, Melos), delivering 10+ reusable packages and a new application shell with zero disruption to production users.
• Rebuilt core user flows (registration, login/SSO, biometric authentication, account activation, bank verification, deposits, cashback) with full feature parity and comprehensive unit test coverage.
• Reduced ANRs, crashes, cold-start time, and UI jank on Android and iOS by conducting 3 performance audits and shipping 40+ targeted fixes.
• Strengthened security and regulatory compliance (GDPR/LGPD) by implementing SSL pinning, geolocation-based fraud checks, reCAPTCHA, WebView hardening, and consent-gated third-party SDKs.
• Integrated crash reporting, logging, analytics, and feature-flag tooling (Luciq, Coralogix, Firebase, Mixpanel, GrowthBook) to improve observability and enable data-driven releases.
• Built and maintained CI/CD release pipelines (GitHub Actions, Firebase App Distribution, TestFlight).

During my tenure at Zendra Health, I was responsible for maintaining and advancing their healthcare mobile ecosystem, leveraging Flutter alongside native Android (Kotlin/Java) and iOS (Swift) to ensure high performance and platform-specific reliability. I successfully integrated legacy native modules into the Flutter codebase, implementing platform channels and refactoring outdated components to create a unified, efficient architecture. In addition, I engineered and maintained backend services using Spring Boot, optimizing API performance, improving security layers, and ensuring seamless interoperability with the mobile applications. A major accomplishment was leading the development and deployment of the Zults application (myrezults.com), delivering a production-grade, scalable healthcare solution adopted in real clinical workflows.
