s²m-tech is operated by the graduated computer scientist stefan schlotterbeck-macht as a part time work. total project time is thus limited and projects typically lead from the basic idea to fully functional prototypes.


s²m-tech provides the creative power and combines it with key skills in hardware, software and computation techniques (fuzzy control, neuronal networks and the like). please check out this site and feel free to contact s²m-tech to discuss your particular questions.

s²m-tech has no regular office times. please contact us by email!
