Kotlin | Jetpack Compose | Quiz & Exam App – Offline & Fast

Developed a modern Quiz & Exam mobile application using Kotlin and Jetpack Compose, engineered for high performance, responsiveness, and a smooth offline experience. The app enables users to take quizzes, create custom exams, and track their scores and progress through a clean, intuitive interface.

The project follows MVVM architecture with Room Database for offline data persistence and Repository pattern for clean separation of concerns. Implemented state management with Jetpack Compose’s State and ViewModel, ensuring real‑time UI updates and efficient recomposition.

Added a dynamic question engine supporting multiple formats (MCQ, true/false, timed questions) and integrated progress tracking with result summaries and scoring logic. Designed reusable UI components, optimized navigation flows with NavHost, and fine‑tuned rendering for a fast, fluid experience across Android devices.

Built for scalability, the app structure allows easy addition of new question packs, analytics modules, or cloud sync in future versions.
