Hey, so here is my bachelor's thesis I worked on for the last semester.

This link should link to the thesis overview page:
https://147.251.49.10/th/qmq62/

it looks pretty sus, but should be safe and working for anyone.

I'll update READMEs with more screenshots and some details I missed when I have some spare time.
