dennis-tra/README.md

Hi, I'm Dennis 👋

I enjoys building things that live on and power the internet.

This year (2026), I've finished my PhD at the Univserity of Göttingen @GippLab and are now working on scaling ProbeLab, a company that I co-founded with @yiannisbot and @cortze.

Formerly I have been working for Protocol Labs and freiheit.com.
