I'm a medical doctor, software engineer and founder. I like to build things.

You can find my rambling on my blog.

Besides that, here's some stuff I've built:

• OpenRegulatory: A medical device compliance SaaS and consultancy. 5 people in total, bootstrapped and 100% owned by me.
• Digital Health Jobs: A job board for, you guessed it, jobs in digital health.
• Beudamed: A better European medical device database. Built in 2 months or so. Note that the EU is still working on their own version of their medical device database with a team of 52 people and a budget of €9M Euros per year.
• Wegzugsteuer.info: A website on Germany's exit tax. Many founders in Germany don't understand the implications of it as you're implicitly locked into staying in Germany once you found a company there (the "Berlin wall" of exit taxes). Furthermore, the tax advisor industry around this topic is very shady and intransparent. I've decided to publish all my notes from my (paid) tax advisor calls there to create some transparency and help people navigate this in a better way.

• KI-Buchhalter (German): An LLM-powered plugin for German bookkeeping software. We're using it at OpenRegulatory and it's saving us a huge amount of time, but.. selling this sort of plugin to other people seems to be tricky.
• Medical Misfits: A podcast in which I interview doctors who don't work as doctors - startup founders, software developers, etc.
