System Administrator & Software Engineer

Free Software Foundation Europe

Who am I?

I am a system administrator and aspiring programmer with a background in political science, philosophy and economics. I am fascinated by all the ways in which technology shapes how we think and interact with one another. Thus, I am concerned about technologies of social control and all the material as well as pyschosocial externalities that result from their global proliferation.

Currently, I work as a System Administrator for the FSFE. Together with a team of passionate free software enthusiasts, I am in charge of ensuring that our free and self-owned IT infrastructure works as reliably as possible. Feel free to check out my contributions there. Maybe you find something useful for your own servers.

I love generating, organising and sharing knowledge. I don’t like if perfectionism gets in the way of publication, so regard this entire website as work-in-progress. Feel free to take a look at the public part of my extended brain.
