🏗️ Architecture & Design Patterns
- ✅ MVVM (Model-View-ViewModel) - Primary architecture for Android apps
- ✅ MVI (Model-View-Intent) - For complex state management
- ✅ Clean Architecture - Separation of concerns with domain, data, and presentation layers
- ✅ Repository Pattern - Data abstraction and single source of truth
- ✅ Dependency Injection - Hilt/Dagger for scalable, testable code
- ✅ Observer Pattern - LiveData, StateFlow for reactive programming
📱 Android Jetpack Components
| Component | Expertise Level | Use Cases |
|---|---|---|
| Room | ⭐⭐⭐⭐⭐ | Local database, caching, offline-first |
| WorkManager | ⭐⭐⭐⭐⭐ | Background tasks, data sync |
| Navigation | ⭐⭐⭐⭐⭐ | Single-activity architecture |
| ViewModel | ⭐⭐⭐⭐⭐ | Lifecycle-aware state management |
| LiveData/Flow | ⭐⭐⭐⭐⭐ | Reactive data streams |
| Paging 3 | ⭐⭐⭐⭐ | Efficient large dataset loading |
| DataStore | ⭐⭐⭐⭐ | Modern preferences storage |
🎨 UI/UX Development
- ✅ Jetpack Compose - Modern declarative UI toolkit
- ✅ Material Design 3 - Latest design system implementation
- ✅ Custom Views - Creating reusable, performant components
- ✅ Animations - Motion Layout, Property Animation, Compose animations
- ✅ Accessibility - WCAG compliance, TalkBack support
- ✅ Responsive Design - Supporting all screen sizes and orientations
⚡ Performance Optimization
- ✅ Memory Management - LeakCanary, memory profiling, bitmap optimization
- ✅ Network Optimization - Retrofit, OkHttp, caching strategies
- ✅ Database Optimization - Indexing, query optimization, background operations
- ✅ App Startup - Lazy initialization, App Startup library
- ✅ Build Performance - Gradle optimization, build cache configuration
- ✅ APK Size - ProGuard/R8, resource optimization
