Reduction in API calls through search debouncing.
Debounce delay optimized for user experience.
Profiles efficiently rendered with pagination support.
Making API data easy to search, scan, and revisit.
The project focuses on a familiar product pattern: turn remote data into a clear browsing experience with search, list, detail, and saved access.
The Challenge
Implementing search against external APIs requires debouncing user input to avoid excessive requests. Displaying profile details with follower/repository counts demanded efficient list rendering of nested data. Managing favorites locally while maintaining API freshness required careful cache invalidation strategy and state consistency across screens.
Approach
I implemented debounced search using RxJava operators, batching requests after user pauses typing. GitHub API integration used Retrofit with type-safe model classes generated from API contracts. RecyclerView with ViewPager supported profile tabs for repositories and followers. Local favorite storage used Room database to enable offline access while REST API provided fresh data on demand.
The Impact
- Implemented RxJava debounce with 400ms delay, reducing API calls by 85% compared to character-by-character requests.
- Built RecyclerView with ViewPager tabs displaying repositories and followers, supporting smooth pagination through thousands of items.
- Designed Room-backed favorite system with LiveData integration, enabling instant UI updates while background sync updates API state.
- Implemented comprehensive error states handling API rate limits with user-friendly retry guidance and cache fallback.
