Hi, I'm Jonas
A Berlin-based freelance mobile developer. I'm an advocate for user-focussed product design, clean code and deliberate software architectures. Here you can find my CV.
TravelSpend is a project that I started myself. It's a budget tracker app specifically designed for travelers and it's available on Android and iOS.
The Monzo app is a completely new approach on managing your finance. It updates your balance instantly, gives intelligent notifications, and is easy to use. I had the pleasure of building the first version of the Monzo Android app.
At Ostmodern I helped building the BBC Player video streaming app. It lets users watch tv shows or download episodes on smartphones and tablets.
Composed was a streaming service for classical music by Universal. As the only Android developer in a small product team I've been responsible for implementing new features as well as maintaining and improving the existing codebase.
This app is one of my personal projects. It is a simple compass navigation app for Android Wear smart watches. It provides beeline navigation for cyclists or pedestrians.
Being part of the Wunder engineering team I developed the initial version of the Wunder ride sharing app. In terms of functionality the app was quite similar to the Uber app.
