Top Rated Plus | $200K+ Earned on Upwork | 100% Job Success | 10+ Years on Upwork I'm an Android Developer and Mobile App Developer with 12+ years of professional experience and a PhD in Computer Science. With $200K+ earned, 100% Job Success, and Top Rated Plus status on Upwork for 10+ years, I build production-ready Android and mobile applications that scale, not MVPs that fall apart under real user traffic. As an Android Developer, my core work covers native Android App Development in Kotlin and Java, full-lifecycle delivery from requirements and architecture through Google Play release, and backend integration with REST APIs, Firebase, AWS, and third-party services. I've shipped apps with 1M+ downloads. As a Mobile App Developer, I also deliver cross-platform solutions using React Native and Flutter when a project needs iOS and Android from a single codebase. As an Android Developer and Mobile App Developer, I've delivered across fintech, healthcare, logistics, social networking, sports, e-commerce, fitness, and entertainment. I also have extensive experience in healthcare and safety applications where data encryption, secure messaging, and compliance are non-negotiable. My architecture approach as an Android Developer is Clean Architecture with MVVM and MVP patterns, Kotlin Coroutines and Flow for async tasks, Hilt for dependency injection, and Jetpack Compose for modern UI. I use RxJava where legacy codebases require it and maintain CI/CD pipelines with Jenkins and TeamCity to keep releases reliable and predictable. As a Mobile App Developer and Kotlin developer, I take ownership of API planning with backend teams, code reviews, refactoring, and full technical documentation so the codebase remains maintainable long after delivery. I work as part of a team at Requestum, which means I can bring in backend, iOS, or QA specialists when a project needs more than one mobile app developer to ship on time. Clients typically work with me when they need: - an Android Developer to build a native Kotlin app from scratch to Google Play release - a Mobile App Developer to deliver iOS and Android from a single React Native or Flutter codebase - an Android App Developer to refactor, optimize, or extend an existing Kotlin or Java codebase - a Kotlin developer who understands Clean Architecture and can own the full technical roadmap - a mobile app developer with experience in fintech, healthcare, logistics, or social platforms If you need an Android Developer who ships production-grade apps and takes full technical ownership, let's talk. Main stack: Kotlin, Java, Android SDK, Jetpack Compose, Android Jetpack, Hilt, Kotlin Coroutines, RxJava, Retrofit, Firebase, AWS, Google Maps API, Stripe, React Native, Flutter, Room, Realm, Jenkins, Docker.

I built Somalia's first mobile wallet. I run a 50-engineer studio.
