At EvoPlay, I built a travel Android app from scratch for flights, hotels, and transfers, with profile customization. I designed its multi-module Clean Architecture using MVVM, MVI, and Kotlin Flow.
I also built offline functionality with multi-tier caching and encryption, and worked through complex gesture and animation issues that had blocked releases. I initiated an incremental migration of the UI from XML layouts to Jetpack Compose.
On KMPProto, I researched code-sharing and UI approaches across Android and iOS, then designed and validated architecture options from native UI with shared business logic to fully shared Jetpack Compose UI. I published the app on Google Play and the App Store.
Earlier, I implemented Android cashier and profile features at GG.BET, and built Android apps at Wouff Digital IT and the independent product Political Square. My earlier technical work included financial dashboards and calculators at VST BANK and enterprise geospatial system integration at Esri Ukraine.
