Having a background in Astronomy and Geophysics, I have moved into IT, quality management and testing over time.

My professional career in the quality area started in 1998. After some years as a commercialisation engineer and tester in the oil industry, I started managing test teams at T-Mobile Germany, where I became responsible for the quality of T-Mobile's charging and billing engine, as well as for other smaller projects. This was quite a task as the software served 40 million customers and I was dealing with one of the biggest Oracle installations in Europe. This part of telecommunications and computing is a fascinating and rapidly changing field, being close to the leading edge of technology.

My focus shifted then to the international scene, where I became responsible for the quality management and testing of all international plattforms of Deutsche Telekom Group Headquarter Services.

Since 2010 I am head of quality assurance at congstar, the young and stylish second brand of Deutsche Telekom in Germany. I got the opportunity to implement quality measures for a lean telco on the green field. This is especially exciting as congstar is totally dedicated to agile methods.

I am now responsible for 16 scrum teams and have learned to scale agile methods when it comes to quality assurance. Modern build pipelines with several deployments a day help us to get fast feedback and improve incrementally. My team is covering different kind of applications, from CRM systems, modern web and Salesforce front ends, billing backends, up to different apps.

Lately I have been focussing on implementing agile methods and Management 3.0 practices in the organisation as a whole. This is challenging but very rewarding. Operating on the executive level allows me to move congstar forward.

I enjoy sharing my experiences as a speaker at a variety of conferences, such as Agile Testing Days, Manage Agile or Agile World.

During my days in the scientific community my main interest was the application of scattered data approximation theory, and the development of 2D-algorithms for real world geophysical data.

Geographically, I am located in Brühl, Germany, where I enjoy life with my wife and my two daughters.

My main areas of interest are:

I am a member of the Society of Exploration Geophysicists, The Planetary Society, and NuHAG.
