About

I’m a penetration tester based in Tübingen, Germany. In a previous life, I studied cosmology with a focus on dark energy at the Institute for Theoretical Physics in Heidelberg. My old site has been preserved by the Internet Archive.

This site is where I write about things I find interesting.

LLM policy: All writings with my name on them have been written by me. I may use LLMs for proofreading, spellchecking or as a thesaurus, but will incorporate suggestions by the LLM manually.
