Senior Software Engineer at Egen

Hi, I'm Siva Nimmala 👋

I build Android apps people love

8+ years building Android apps with Kotlin and Jetpack Compose, from retail and smart-home apps to banking apps used across Africa and Asia. In my own time I make Music 7 and UniUI, two apps on Google Play.

Apps I design, build and ship

Two apps I build end to end, from design and code to the Play Store listing. Both are written in Kotlin and change their whole look with a theme, not just the colours.

Music 7

Music player · Android

A music player that changes its whole design with your mood: a spinning vinyl, a turning cassette, a glowing cyber display and more. Play your own songs, stream from your Jellyfin server, explore charts and world radio, and watch your music come alive.

UniUI NEW

Home screen launcher · Android

One home, 36 worlds. Every UniUI theme changes the layout, widgets and icons: a daily newspaper, a pixel game with quests, an aquarium you can feed, a garden with butterflies. Add rain, snow or a starry night on top of any of them.
