Led the migration of four native applications to Flutter, defining reusable architecture standards and accelerating cross-platform delivery. Built and launched new versions of the Ingresse and Backstage apps, reducing system-wide bugs by 80%. Designed and implemented an offline-first approach with local persistence to support ticket validation and sales in low-connectivity scenarios, including Smart POS devices and kiosks. Integrated Flutter with native Android (Kotlin) and iOS (Swift) via Method Channels and FFI for hardware-specific capabilities. Owned CI/CD with GitHub Actions and Fastlane for automated builds and store deployments, and introduced automated testing (unit, mocks, UI) to increase release confidence while applying mobile security best practices for secure storage and token handling.

Developed and evolved a large-scale reseller mobile app in Flutter supporting critical sales and operational workflows, including offline-first capabilities. Integrated third-party SDKs such as facial recognition (Unico) to support secure authentication. Contributed to BFF/API development using Node.js and NestJS to improve mobile-backend integration efficiency. Led a critical reseller workflow using Flutter/JavaScript interoperability, significantly reducing a projected 3-year delivery to 1 month. Also integrated Flutter modules into existing React web platforms to enable cross-platform feature reuse.

Led the technical evolution of Ingresso (consumer app) and Backstage (box office app), and built new versions of Awai Ingresso and Awai Backstage, reducing system-wide bugs by 80%. Adapted applications to run on Smart POS devices and physical kiosks, and implemented local data persistence for tickets and products to enable offline operation and improve reliability. Directed a migration from native apps to Flutter with defined architectural standards. Contributed to backend APIs and integrations using Go and Node.js, and used AI tools to support feature planning, workflow design, and engineering automation. Collaborated across teams to deliver high-quality mobile solutions, improving code organization, maintainability, and application performance.
