Kotlin
Jetpack Compose (Declarative UI)
MVVM + Clean Architecture Principles
Room Database (Offline Persistence)
Kotlin Coroutines + Flow (Reactive Programming)
Navigation Compose (Type-safe routing)
- Unidirectional Data Flow (UDF) Instead of scattered states, the app follows a single QuizUiState, ensuring predictable and debuggable UI behavior.
- Scalable MVVM Implementation Clear separation between UI, business logic, and data layers improves maintainability and testability.
- Optimized Local Persistence Room is used with suspend functions and background threading to eliminate UI blocking.
- Shared ViewModel Strategy A single ViewModel instance across screens ensures real-time UI sync without manual callbacks.
