My expertise spans end-to-end app development, from architecture design and feature implementation to deployment and performance optimization. I specialize in Kotlin-based Android development using the latest Android Jetpack and Material 3 components. I’ve successfully migrated and developed applications using Jetpack Compose, Navigation Component, Room, WorkManager, Paging 3, and ViewModel with MVVM, MVI, and Clean Architecture patterns. I have also worked extensively with Dependency Injection (Hilt/Dagger 2), Coroutines, Flow, and gRPC/WebSocket for real-time communication. My experience includes building large-scale apps involving complex domains such as: Live calling, music, and video streaming (WebRTC, gRPC, ExoPlayer) Location-based and map-driven apps (Google Maps, Fused Location, Geofencing) E-commerce and loyalty apps with in-app payments, analytics, and deep linking Social networking features, chat systems, push notifications, and Firebase integration Offline-first architectures using Room and data synchronization patterns I’m also familiar with modularization, dynamic feature delivery, and multi-module clean architecture for scalable enterprise apps. My backend experience includes integrating with REST/gRPC APIs, Firebase, GraphQL, and Cloud Functions, ensuring seamless communication and optimized network usage. With strong analytical and problem-solving skills, I focus on delivering apps that are robust, efficient, and aligned with modern Android development standards. I take pride in writing clean, maintainable, and testable code following SOLID principles and unit/UI testing (JUnit, MockK, Espresso) practices. I’m seeking opportunities to contribute to challenging Android projects that demand creativity, deep technical expertise, and ownership. I can commit 40+ hours per week and ensure top-quality results, timely delivery, and a long-term professional relationship.
