• Developed a production-grade restaurant POS app using Kotlin, Jetpack Compose, Material 3 with custom MVI architecture, integrating 15+ RESTful APIs via Retrofit for end-to-end order lifecycle management across multi-outlet operations. • Engineered real-time sync via OkHttp WebSockets with auto-reconnect and 20s heartbeat, plus a debounced optimistic update pipeline (500ms batching + Mutex concurrency) using Kotlin Coroutines for UI responsiveness under intermittent connectivity. • Architected 5 feature modules with Hilt DI, secure JWT auth with transparent token refresh, multi-layer caching (in-memory + SharedPreferences), and Navigation Compose routing — reducing redundant API calls and enabling offline-first functionality.
