Tolga EGE

Android App Development

Modern, performant Android apps with Kotlin and Jetpack Compose, supporting a wide device range.

Android app development is software production for smartphones, tablets, TVs and wearables using Google's Android OS. Android has 75%+ market share in Turkey; it's a critical platform for reaching a wide audience.

As Tolga Ege we develop apps from MVP to enterprise with Kotlin, Jetpack Compose and Android SDK. We have deep experience with Coroutines, Flow, Room DB, Hilt DI, Material Design 3 and Google Play release processes.

Device diversity (different screen sizes, OEM features, OS versions) and fragmentation are challenges in Android development; we overcome these with modern testing and emulator matrices.
