The “r/Android App Store” is an Android application that allows users to conveniently browse a massive community-curated list of apps including all sorts of Android applications and games. The app features a comprehensive featureset and boasts a very strong userbase - the app has almost 100,000 cumulative downloads. With over 20 merged pull requests, some of my contributions include:

• new features such as a complete redesign of one of the app’s pages, the ability to automatically tag newly added apps as “new”, the ability to save selected filters, a popup to show changelogs pulled from GitHub, markdown to HTML conversion for text, and more
• refactoring parts of the app’s backend to utilise Dagger’s dependency injection capabilities to enable easier testing, as well as making performance improvements by providing application-scoped (singleton) OkHttpClient and Retrofit instances through Dagger (related blog post)
• rewriting unit tests using JUnit and Mockito for one of the refactored modules for more comprehensive coverage, and provided unit tests for some of my own contributions
• a wide range of bug fixes to improve the app’s stability
• integrating test coverage reporting into the project’s CI tool, Travis, using Coveralls
• reviewing pull requests made by new contributors and addressing bug reports and issues raised by the community
