Shushan M.

Android developer with 10+ years of experience, building apps for both Android and iOS. I work on a large government services app with millions of users (Kotlin, Jetpack Compose, multi-module), and I built and published my own app, Wisekins, on both Google Play and the App Store using Kotlin Multiplatform. What I can do for you: • Port iOS apps to Android (or the other way round) with the same look and feel • Build new apps in Kotlin + Jetpack Compose, or for both platforms with Kotlin Multiplatform • Fix bugs, improve and maintain existing apps, even large codebases I didn't write • Add ads and in-app purchases: AdMob, subscriptions (Google Play Billing, App Store, RevenueCat) • Take care of Play Store and App Store releases and reviews Tools & tech: • Languages: Kotlin, Java, Swift basics • UI: Jetpack Compose, Compose Multiplatform, XML layouts • Architecture: MVVM, Coroutines/Flow • Data: Room, SQLite, Realm • Networking & APIs: Retrofit/Ktor, Firebase, Google APIs (Maps, YouTube, Calendar), Facebook & Twitter APIs • Monetization: Google AdMob, Google Play Billing, RevenueCat • Git (GitHub, GitLab, Bitbucket) I reply fast, share progress regularly, and write clean code that's easy to hand over.
