Android Developer Profile

John Ralph Dela Rosa

Profile photo
I am a dedicated Android Developer with 3 years of hands-on experience building mobile and TV applications using Kotlin. My professional work primarily involved legacy UI (XML-based), but I have actively upskilled through personal projects using Jetpack Compose and modern practices. I specialize in MVVM and Clean Architecture, leveraging tools such as Hilt, Retrofit, and Coroutines to deliver scalable and maintainable applications. With a strong focus on performance, code quality, and user experience, I’ve contributed to end-to-end development of Android and Android TV apps. I am passionate about continuous learning, exploring backend integration (e.g., Supabase), and applying modern approaches such as testable architectures and TDD principles to produce reliable and polished applications.
