Kotlin.
Compose.
Multiplatform.
I have developed mobile applications since 2006 and native Android apps since the platform's early versions. Today, my focus is Kotlin, Jetpack Compose, and Kotlin Multiplatform. I work with teams in Vienna, Klagenfurt, and remotely.
Native apps
for Android.
Android is an operating system and software platform for phones, tablets, wearables, TV, cars, and embedded devices. It is based on a Linux kernel; native app development today is primarily Kotlin, while older codebases often still contain Java.
I help with concept, architecture, implementation, modernization, and publishing of native Android apps - from existing Java/XML projects to modern Kotlin and Jetpack Compose codebases.
What I
bring in.
What I use.
Mobile apps
since 2006.
My experience spans early Java and Android projects, native iOS development, and modern Kotlin and Compose codebases. I also bring long-standing experience with Ionic, Cordova, and Capacitor. That breadth helps when deciding whether native Android, Kotlin Multiplatform, or another cross-platform approach is the right long-term choice.
I see AI as a tool, not a replacement for engineering responsibility. I use Claude Code, GitHub Copilot, OpenAI Codex, and Google Gemini to support code quality, evaluate architecture decisions faster, and reduce repetitive work.
I founded AndroidHeads Vienna, a community of more than 600 Android developers in Vienna, and co-organize droidcon Vienna, sponsored by JetBrains.
Android & Compose.
2026: Advanced Compose Course, JetBrains / kt.academy.
2022: Google Play Store Listing Certificate, Google Play Academy. Certificate ID: 47262528.
Also cross-platform.
Besides native Android, I also work with Ionic and Capacitor when that is the right fit for a project.
Android development, architecture review, modernization, or Google Play release: send a short note about the situation. I will get back to you for an initial conversation.
