I’ve been working with Stefan for building a large wiki containing information about entertaiment technologies. Stefan has the ability to kick off projects and bring them to a successfull end. He is focused and open minded at the same time, which made working with him really enjoyable and productive. I’d work with him anytime again.

Over the past years i have worked on a number of projects with Stefan Johannesberg. Stefan is passionate and professional in his work and a great team player. I would not hesitate to jump into a next project with him.
