FAQ
Do you build in Kotlin or Java?
Both. New Android app development is written in Kotlin with Jetpack Compose by default. I also maintain and modernise existing Java Android apps, including Java-to-Kotlin migration.
Can you build the iOS version too?
Yes. I use Kotlin Multiplatform (KMM) to share business logic across Android and iOS, with a native SwiftUI interface on the iOS side. Message me and I will quote both platforms together.
Will I get the source code?
Always. You receive the full Android Studio project, the signed APK/AAB, and a short handover document. The code is yours with no lock-in.
Can you publish the app to the Google Play Store?
Yes. Play Store upload, store listing setup, content rating and release management are included in the top package, or available as an add-on.
Do you integrate Firebase, REST APIs or payments?
Yes - Firestore, Realtime Database, Authentication, Push Notifications, Retrofit/Ktor REST integration, AdMob, and in-app purchases or Stripe.
