After my studies at the Vienna Technical University I dedicated myself completely to the project Notebookcheck as a co-founder. Since Commodore C64 and Atari 1040 ST, computers have been an integral part of my daily activities. Beside new technologies, especially electric mobility, my interest also belongs to architecture and construction engineering.
