About

Hej, I am Markus and live with my wife Sophia and our cretan hound Friedel in Hamburg.

I enjoy to discover things and keep honest in what I am doing. In my physics study I realized, that re-inventing or solving things, that are solved, is not unnecessary. It will lead to certain points where you really invent something new without striving for it artificially. In my data science study I learned that being greedy leads to local minima, nothing that pays off long term.

Please feel free to send me an email with any feedback, questions, suggestions or without any context.

Best regards
