I own Android development in an internal mobile studio: technical decisions, implementation, monetization integrations, and Google Play delivery.
Product ownershipArchitectureCI/CD
Android ownership — my scope +
In a two-developer team, I own Android while my colleague owns iOS. We share product discovery and monetization planning.
I’m also developing a reusable Android starter to make foundations such as analytics, billing, and configuration easier to reuse across products.
Current work · Galaksion. The starter is in development.
02 / ABOUT ME
Engineering with
the product in mind.
I’m Evgenii, an Android engineer based in Tbilisi. I enjoy working where mobile engineering meets product decisions — understanding what to build, making it reliable, and getting it into people’s hands.
My work spans Kotlin and Jetpack Compose, app architecture, subscriptions, analytics, and release automation. I’m interested in Android engineering opportunities in the US, Canada, Europe, and the UAE.
03 / EXPERIENCEExperience behind the work.
Android delivery across product development, real-time features, and mobile infrastructure.
