My work

An excellent user experience is always in the center of my work because I’m convinced that intuitive and easy-to-use apps are used more often and will be the ones that survive in the market.

Here you find an overview of my work during the last twenty-five years. I have written millions of lines of code, created countless designs and trained so many people, it would be too much too list everything. What follows is a summary of the projects I am most proud of in my career.

2019 Aliens Bring Change

In 2019 I started a game studio in Berlin. I make games for Windows 10 and Android. Among the titles are Mahjong Solitaire, Solitaire Battleships, Solitaire Cards, Memory and many others.

2017-2019 Microsoft Mixed Reality Studio

As Senior Software Engineer for the Microsoft Mixed Reality Studio in Berlin, I created Holographic Applications for Hololens for our customers in Germany. For Toyota Material Handling, I programmed the application flow for a Holographic Warehouse Simulation, here demonstrated by Satya Nadella, the CEO of Microsoft:

Hololens for games

The Hololens is also a fantastic gaming device. The following video is of a hobby project I created in my spare time. I use my XBOX controller to move a holographic fish through the office:

2017-2019 App development for everyone

App development for everyone is a free training that I organise via a meetup in Berlin. During this training you learn how to program with technologies like Javascript, Python and C#. It doesn’t matter whether you are a beginner or have some experience and want to brush up your skills.

You will learn the basics about programming languages, platforms, variables, loops, datatypes, statements and expressions. While learning these basics, we will gradually build an app or game together!

2015-2017 Microsoft Todo

Microsoft To-do, the sucessor of Wunderlist, built to integrate with and use Exchange Online.

Microsoft Todo

Wunderlist had a huge fan base and in 2016 it was officially replaced with Microsoft Todo. Having worked on both products, it was a proud moment to see the announcement in the Berlin subway.
