I'm an inventive full stack developer with over 10 years experience creating reliable and user-centered products. My passion is finding new ways of using data and technology to solve life's problems and challenges.
I have great interest in all things tech and I'm a firm believer in life-long learning. I know what it means to take ownership, deliver measurable results and value being part of a great team.
I worked in the corporate world on three continents, founded my own consultancy and co-founded a start-up early in my career.

Steffen is the most versatile programmer I have worked with during my years at SAP. He combines his excellent programming skills with a great sense of detail for design and the user experience behind the data and the interface. His beautiful dashboards are being used by the board as well as in day-to-day operations by thousands of happy users. An Apple addict, his list of tech gadgets of all sorts is also impressive - not only work related. I would hire Steffen on the spot. PS: And kudos for fluently speaking the most difficult (and the easiest) language in modern day business!
