Over four months, this developer enhanced the CreaMakers/changli-planet-app by delivering an offline-first student timetable and course scheduling system, migrating from a network-only approach to robust local persistence using Kotlin and the Room database. They refactored UI components and navigation, introduced Redux-based state management with RxJava for asynchronous operations, and improved onboarding by binding student credentials. Their work included semester switching, week handling, and per-user caching for electricity bill queries, while also stabilizing release builds through improved Gradle configuration. By establishing fragment-based scaffolding for new features, they enabled scalable development and improved user experience across Android and Java codebases.
