About Me

Hi, my name is Alex "W4RH4WK" Hirsch and I am a researcher at the University of Innsbruck. I am part of the Distributed and Parallel Systems Group of the Computer Science institute and tasked with the research and development process of the Insieme project. Before joining University I graduated at HTL Anichstraße (Applied Computer Science and Electronics) – so I know my way around computer related stuff as well as electronic circuitry.
