About

A mobile engineer who balances architecture, UX, and delivery.

I focus on Android first, but I also work comfortably in Kotlin Multiplatform when a product needs shared mobile capability across Android and iOS.

I can also deliver Flutter applications using BLoC architecture. Flutter BLoC and Kotlin Multiplatform are handled as separate tracks, so architecture decisions stay clear and do not overlap.

In practice, I can help teams ship and maintain both Android and iOS experiences with a consistent product quality bar.

My approach is practical: keep the architecture clean, ship UI that feels modern, protect sensitive flows, and make the app reliable for real-world users in production.
