Welcome!

Since my education as a photographer I work in an interdisciplinary environment between media and technology but also computer science and classical engineering. The interconnection of those disciplines I consider an interesting challenge and an opportunity to concentrate on new subjects. Nevertheless I emphasize on focused treatment of tasks and the therefore needed know-how.

Corresponding to the following, I describe myself as a professional problem solver.

My professional objectives I see as a teamleader and in project management. During my work at viception I was able to acquire a broad base of experiences as well in development as in project management and team leading. In future my concern is to formalise and strengthen these experiences by leading larger or even international teams. While conceptional work and the work or exchange with other people are inspiring to me, new innovative topics and ideas are pushing me forward.
