I’m a Senior Native Android Engineer with 10+ years of experience building, scaling, and optimizing Android applications used by thousands to millions of users. I specialize in: • Building Android apps from scratch (architecture → production → scaling) • Taking over legacy codebases and modernizing them • Improving performance, stability, and user experience • Architecting clean, testable, and maintainable systems I write production-grade code that is built to last. ⸻ 🧠 What You Can Expect Working With Me ✔ Clean Architecture (MVVM, MVI, Modularization) ✔ Kotlin-first development ✔ Coroutines & Flow ✔ Testable code (Unit + Integration tests) ✔ CI/CD friendly structure ✔ Performance optimization & memory management ✔ Pixel-perfect UI aligned with Material Design I don’t just “make apps work.” I build apps that scale, perform, and are easy to extend. ⸻ 🔧 Technical Expertise Core Android • Kotlin, Android SDK, Gradle, Android Studio • Jetpack (LiveData, ViewModel, Navigation, Room) • Coroutines, Flow, RxJava • Dependency Injection (Dagger / Hilt) Architecture & Scale • Modularized architecture • Clean Code, SOLID principles • CI/CD workflows • Large-scale app optimization APIs & Backend Integration • REST & GraphQL APIs • Retrofit, OkHttp • AWS (Cognito, AppSync, Amplify, S3, DynamoDB) • Firebase (Auth, Analytics, FCM, Storage) Advanced Integrations • Payments (Stripe, PayPal, Google Billing) • Google Maps, Geofencing, GPS • Real-time chat (XMPP, PubNub, QuickBlox) • Push notifications • Social media integrations Platforms • Android TV & Amazon Fire TV ⸻ 💼 How I Work I communicate clearly, meet deadlines, and take ownership of outcomes — not just tasks. Whether you need: • A full Android app built from idea to launch • A senior engineer to audit and refactor your codebase • Performance and crash optimization • Feature expansion in an existing app I’m here to help. I’m comfortable working across time zones and collaborating with distributed teams. ⸻ If you’re building something meaningful and want a senior engineer who treats your product like their own — let’s talk.
