I am experienced in a variety of programming languages. I enjoy helping peole solve their programming-related issues while also explaining it to them in an easy to understand way. I have a masters degree in Machine Learning and so am particularly proficient in ML implementation such as predictive data analysis, cluster analysis, big data and data visualisation (and more). I also have advanced knowledge of network analysis techniques using graph databases such as Neo4J.
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. For me, a computer should aim to automate everything that is boring, such that one can pay more attention to what is interesting in life. After each session, I aim to write a document (usually within one week) that describes what we discussed.
