Hi, I’m Johannes Filter! 🙋🏻‍♂️

I use technology as a tool for social progress and I am into open-source software.

I am an independent researcher, software developer and data analyst. My work is focused on human-computer interaction, machine learning and natural-language processing. Currently, I am freelancing so contact me for future collaborations. Besides, I hold a master’s degree in computer science from the Hasso Plattner Institute in Potsdam, Germany.

I am an activist for more transparency in the public sector and I am part of the German open data and civic tech community. Together with FragDenStaat, I fight for freedom of information and I frequently participate in projects of the Open Knowledge Foundation Germany such as Code for Germany and Offene Gesetze. Because I still believe in the liberating effect of open-source software, I regularly contribute to it on GitHub.

To generate knowledge, I blog about tech in English. Also, I write about my adventures with German freedom of information laws on the FragDenStaat blog.
