PROFILE
Lei Chen
Chenlei contributed to the BrewR-EPFL/BrewR repository by developing features that enhance user experience and streamline backend processes. Over two months, Chenlei built and refactored Android screens such as ExploreScreen and UserPrivateListScreen, integrating Google Places API to fetch and display nearby coffee shops with improved data modeling in Kotlin. The work included implementing location-based search, favorite shop management, and robust error handling, while optimizing API usage and automating CI/CD pipelines with Gradle and GitHub Actions. Chenlei also strengthened the testing suite using Mockito and Jetpack Compose Testing, ensuring code quality through consistent formatting and comprehensive test coverage across the 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.
