Living and breathing Clojure and functional programming. I value craftsmanship, I am genuinely interested in technology and computers. I have a particular focus on Clojure, Linux and Emacs and data-oriented programming. Experienced with full-stack web applications, cloud backends, CI/CD, language design, tooling and making open-source contributions. Fluent in English and German. I am frequently praised for my high enthusiasm and open-ended curiosity about technology and computers. Committed to delivering solid information systems and understanding the problem, iterating on the ideas, and communicating effectively as a programmer.
