Jan-Philipp Litza


Computer scientist, mathematician and open source enthusiast from Bremen, Germany. Interested in internet politics, privacy and IT security.

Programming, Networks and Open Source

Computer science was my minor subject and thus a significant part of my studies, but also was my hobby long before and it still is. I busy myself a lot with computers, networks, security and Open Source, not only in my spare time but also as programmer / administrator at PLUTEX. Some results can be found at my Github profile. Since the end of 2013 I’m founder and one of the main developers and organizers of the “Freifunk Bremen” project.


I studied mathematics at the University of Bremen between 2009 and 2015. In September of 2012 I received my Bachelor of Science, in March of 2015 my Master of Science. Following this, I was a research assistant at the ALTA institute until 2017.
