Resume

Living and breathing Clojure and functional programming. I am genuinely interested in technology and computers and value craftsmanship. I have a particular focus on Clojure, Linux and Emacs and functional, data-oriented programming.

Experienced with full-stack web applications, frontend, react, clojurescript, backend, cloud infrastructure, CI/CD, language tooling and making open-source contributions.

Committed to delivering, understanding the problem, iterating on the ideas, and communicating effectively as a programmer.

Fluent in English and German. I am frequently praised for my high enthusiasm and curiosity.
