Developer by day, programmer by night. I obtained a master of science in civil engineering (computer science) and participated - together with several teams - in programming contests and hackathlons. I answer questions on StackOverflow on a daily basis and wrote courses on Artificial Intelligence and Digital Electronics. I am mainly interested in Haskell, Python, and Prolog. I worked as a researcher in the field of hyperheuristics (artificial intelligence), a teaching assistant in computer science and as a data scientist and technical lead developer in an AI startup. During my spare time I developed small (and larger) projects to help with daily routine.
