Web & Android Developer

I build for the web, Android, and the system beneath it.

I’m Rono—a Kotlin-first Android developer who also builds responsive web interfaces and works with AOSP and crDroid custom ROMs.

02 / About

Across the whole stack.

I enjoy building the interface people see, the native Android app they use, and the system layer that makes it all work.

My work starts with clear, usable experiences and goes deeper when the problem calls for it. That means responsive web development, Kotlin and Java on Android, and hands-on work in the AOSP/crDroid ecosystem.

I value readable code, practical solutions, good performance, and learning by building.
