Planki App
Makes the plank exercise more enjoyable: catch fireflies instead of staring at the plank timer.
Senior Mobile Engineer @ DAK-Gesundheit
Currently living in Hamburg. Besides professional mobile app development, I like electronics and security related projects.
In my full-time job, I'm developing Android applications, in my spare time, I also work on iOS applications.
Since I have worked for more than 10 years in the mobile field, I have experience with most of the mobile SDKs and technologies (Kotlin+Coroutines / Swift+Concurrency, Compose / SwiftUI, MVVM and typical frameworks). I also write backends in Kotlin using Ktor and SQLDelight / Exposed for database abstraction.
I like to work in a precise and detailed way to achieve high product quality. Also, I have a lot of experience writing clean code (shout-out to Robert C. Martin) and also keeping the code clean (which is often a lot more effort). Furthermore, I'm highly interested in cryptographic topics, so I build up a lot of knowledge in this field as well.
In the past, I worked for Audi to develop the myAudi app (1M+ users) from the ground up. After various smaller apps in different industries, I am now working for one of the biggest health insurances in Germany to develop the DAK App (also 1M+ users).
