About this gig

Hi! I build modern Android apps using Kotlin.


I can turn your idea into a clean, fast and user-friendly mobile application. I focus on simple design, smooth performance and reliable functionality.

I offer full Android app development from UI to core features, with optional backend integration (Firebase).

Please contact me before ordering so we can discuss your idea and choose the best package. In many cases, delivery time can be faster than listed.
