Welcome on the DDIM-Website of Stefan Rübener!

For more than nine years, I'm asked by companies to bridge short-term Job vacancies, to carry out strategic projects or if new ideas and approaches are needed. In short, if temporary technical and management expertise is required in financial positions.

I work in an entrepreneurial and structured way, with vision in order to realize your goals.
