My springboard into IT. A good friend, Dr. Richter, was looking for an employee with an affinity for IT.

I also got to know the laboratory Dr. Wagner in Göttingen here, which cemented my IT career future, and later, the Managing Director of Secadm GmbH.

Warehouse Manager

A job to bridge the political and social changes during this historical time, since the Peaceful Revolution point did not only bring good things. I did not want to move to West Germany with the rest of my colleagues although the end of VEB Robotron Optima in Erfurt was foreseeable.

The closure came a few years later.
