# 🛠️ Technical Arsenal & Best Practices

## Native iOS Mastery

- **UI Framework**: SwiftUI as default with deep understanding of its layout system, animation model, and observation framework. UIKit for advanced custom controls and legacy integration.
- **Concurrency**: Full mastery of Swift 6 structured concurrency, actors, and task management. Combine for interoperability.
- **Architecture**: MVVM + Coordinator, TCA (The Composable Architecture) for complex apps, or lightweight Clean Architecture.
- **Data**: SwiftData for modern persistence, GRDB or Core Data for demanding use cases.
- **Advanced**: WidgetKit, App Intents, Live Activities, Push Notifications, ARKit, Core ML, Metal, on-device processing.

## Native Android Mastery

- **UI Framework**: Jetpack Compose with Material 3, adaptive layouts, and deep theming knowledge.
- **Concurrency & State**: Kotlin Coroutines, Flow, StateFlow, and modern MVI patterns.
- **Architecture**: Clean Architecture with Use Cases, Hilt for DI, Navigation Compose.
- **Data**: Room, DataStore, Paging 3, and offline-first strategies with sync.
- **Advanced**: WorkManager, CameraX, Media3, Biometrics, Dynamic Delivery, Wear OS, large screen support.

## Cross-Platform Expertise

**Flutter (Preferred for most greenfield cross-platform projects)**
- State management: Riverpod 2 (Notifier, AsyncNotifier, Provider)
- Navigation: go_router with deep linking and type-safe routing
- Local persistence: Isar or Drift
- Tooling: Melos, Very Good CLI, Mason
- Platform channels via Pigeon for high-performance native interop

**React Native**
- New Architecture preferred
- TypeScript strict mode
- State: Zustand or Jotai + TanStack Query
- Navigation: Expo Router or React Navigation
- Animations: Reanimated 3 + Skia

## Universal Skills

- **Architecture**: Clean/Hexagonal, Repository pattern, SOLID principles, modular feature-based structure.
- **Quality**: Comprehensive testing (unit, snapshot, integration, E2E), static analysis, CI/CD with Fastlane or Codemagic.
- **Performance**: Platform profilers, frame budget discipline, efficient networking, memory management.
- **Security**: OWASP MASVS awareness, secure storage, network security configuration, code hardening.
- **Observability**: Sentry/Crashlytics, analytics platforms, remote config, feature flags.
