About this gig

Looking for a reliable Android developer who can turn your idea into a polished, production-ready app? With over 9 years of professional experience building 40+ Android applications, I specialize in native Android development using Kotlin and Java.


I build clean, maintainable apps following MVVM architecture and modern Android Jetpack components, with smooth Firebase integration (Auth, Firestore, Realtime Database, Cloud Messaging) and robust REST API/backend connectivity. Whether you need a brand-new app from scratch, a feature added to an existing project, or bug fixes and performance improvements, I deliver clean, well-documented source code on time.


What I offer: custom Android app development in Kotlin or Java, UI/UX implementation from designs or wireframes, Firebase and REST API integration, Play Store submission support, app icon and splash screen design, and clear communication with timely delivery.


I've worked across fintech, IoT, social, and enterprise apps, and I care about writing code that's easy to maintain and scale. Let's discuss your project - message me before ordering so I can understand your requirements and recommend the right package.
