Sebastian Hahner

TL;DR: I am a researcher at KIT Karlsruhe. I’m web video creator since 2010. I studied computer science, I stream live while coding, and I love playing around with new technologies.

I uploaded 4000+ videos that were viewed ~60 million times, I lead many open-source software projects, and I host the German podcast while(true) since 2018. I co-authored 25+ peer-reviewed publications, many of which were published at high-ranked venues including ICSE, SEAMS, ICSA, and ECSA. You can find what I’m currently up to on my now-page or read the full story. Don’t forget to say Hi! via mail or using the platform of your choice.
