About

Self-taught, production-tested.

I started building Android apps as a freelancer in 2019, learning by solving real client problems and shipping apps for real users. Six years later I've worked across product companies on apps in navigation, translation, AI imaging, PDF tooling, weather, finance, TV remotes and utilities.

Most of my work has been on apps with real users at real scale — which means the interesting problems aren't the features, they're the crash rates, the ANRs, the Play Console policy changes, the cold-start times and the migrations that have to happen without breaking a million existing installs.

These days I write Kotlin with Jetpack Compose, keep domain, data and presentation strictly separated, and mentor junior developers on the same. Outside of my full-time role I design and ship my own apps end to end under TenDegree — architecture, UI, release management and everything in between.
