Tobias Boehm

I am a Senior Mobile Developer (Android + iOS) with over 12 years of experience. I build native apps with Kotlin and Jetpack Compose, as well as Kotlin Multiplatform (KMP + CMP).

My projects are used by millions of users: the outdoor app komoot (10M+ downloads), the electronic health record (ePA) at IBM, RTL+ streaming, Congstar, Immowelt, and the AOK bonus app. From this work, I know what large teams and regulated industries truly need: robust architecture, security (Certificate Pinning, sensitive health data), and code that remains maintainable even in five years.

This is how I can support you:

- Team Augmentation: I integrate seamlessly into existing Android teams and deliver from day one (SCRUM, SAFe, Clean Architecture).

- Modernization: I migrate established apps to Clean Architecture, modularization, and Jetpack Compose, including Quality Gates (ktlint, detekt, Tests).

- End-to-End: From idea to MVP to launch, app and backend from a single source (Ktor, Google Cloud, Firebase).

- AI Features: Generative AI in mobile apps (OpenAI, Stable Diffusion, Flux), proven in my own product MNDXT.

My Stack: Kotlin, Jetpack Compose, Coroutines, MVVM/MVI, Hilt/Koin, Room, Retrofit/OkHttp, Kotlin Multiplatform (KMP), Firebase, Ktor. iOS via CMP as a secondary platform.

What you get: a senior who thinks along instead of just executing, communicates clearly, and takes responsibility, from concept to stable release. Remote in the DACH region, on-site in Northern Germany if desired.
