PROFILE
Lei Chen
Over a two-month period, contributed to the BrewR-EPFL/BrewR repository by building and refining features for an Android application focused on discovering and managing coffee shop information. Developed user-facing screens such as ExploreScreen and UserPrivateListScreen, integrating Google Places API and Firebase Firestore to fetch and persist coffee shop data. Enhanced navigation flows, implemented mechanisms for saving favorites, and improved UI responsiveness. Applied Kotlin and Java for core development, leveraging Jetpack Compose for UI and Gradle for build automation. Strengthened code quality through expanded test coverage, CI/CD improvements, and consistent code formatting, resulting in a more stable and maintainable codebase.

Nov 1, 2024Month: 2024-11 BrewR monthly summary: Key features delivered include FetchNearbyCoffeeShops (Google Places API) with a 20-result cap and migration to returning Coffee objects, plus a refactor of ExploreScreen to align with real data. Major reliability improvements were made to the location/nearby-fetch flow (GetCurrentLocation now precedes fetchNearbyCoffeeShops; stability enhancements) and API usage controls (limit to a single coffee shop per fetch) with added exception handling. UI polish and build/CI improvements reduced release risk, with updates to app logo, map icons, and default no-image handling, alongside comprehensive CI/test hygiene and formatting improvements. These changes collectively improve user experience in nearby search, reduce API costs, and boost developer velocity through better tests, formatting, and automation.
