Rust Server

The website you are looking at is being served by a handcrafted backend written in Rust using the Rocket framework. It packages the assets into a binary and serves them ultra-efficiently. It also takes care of relaying messages to me without exposing my email to the depths of the web.

About me

I am a web developer based in the Cologne-Bonn area in Germany. I'm currently looking for opportunities to work and learn within a motivated team and on challenging projects. My favorite programming language is currently Rust, but I also like and use TypeScript and Python, and as an Emacs user have a soft spot in my heart for Lisp. I am always learning new things, if it's not about web technologies then natural languages and music.
