How I work

A generalist Android engineer who cares about the details.

Kotlin‑first

Idiomatic Kotlin, coroutines, flows — with Java interop when the codebase calls for it.

Compose + XML

Comfortable across modern Jetpack Compose and legacy XML view systems.

Ship & iterate

Play Store releases, crash triage, and performance tuning as a routine.

UI craft

Close collaboration with designers to land pixel‑honest, delightful screens.

Got an idea for an Android app?

I take products from concept to Play Store, and I'm always up for a good conversation about what to build next.
