About Me

Hi! I'm a Berlin-based software engineer.

I've built things with Node, React, Redux, Elixir, Ruby, Rails, and PHP/MySQL.

I'm interested in developing sustainable web applications, robust RESTful APIs, playing with emerging technologies, functional programming languages (in particular MLs and Lisps), test-driven development, and responsive HTML/CSS interfaces.

I'm on Github and Linkedin.
