Contributed to the BrewR-EPFL/BrewR repository by delivering user journey management, recommendation features, and UI enhancements for an Android application. Developed end-to-end tested flows for journey exploration and management, integrating user-scoped data storage in Firebase Firestore to ensure data isolation. Applied a coffee-themed UI palette and added profile photo fallbacks to improve user experience and branding consistency. Enhanced code quality through ktfmt-based Kotlin formatting and refactored repository methods for clarity. Implemented a KNN-based recommendation system with a dedicated ViewModel and screen, while expanding test coverage using Mockito and Jetpack Compose to support maintainability, reliability, and faster feature iteration.
