What I'm looking for

I seek senior Android roles or technical lead positions where I can modernize mobile apps, mentor engineers, and deliver high-performance, maintainable Kotlin/Compose solutions.

I am a Senior Android developer with extensive experience leading full lifecycle mobile projects, modernizing legacy apps, and implementing modular, testable architectures using Clean Architecture and MVVM. I drive UI modernization with Jetpack Compose, migrate Java codebases to Kotlin, and optimize performance through profiling, resulting in measurable improvements on low-end devices.

I lead teams technically and mentor junior engineers while integrating tools like Dagger Hilt, Room, Retrofit, and Coroutines/StateFlow for scalable, responsive apps. I hold a Systems Engineering degree and a Scrum Foundations Professional Certificate, and I prioritize code quality, maintainability, and offline-first reliability in production mobile apps.
