Dear recruiters, please don't contact me with any current job offers. At the moment, I am extremely happy working at ioki.

Starting 2023, I will be looking for a new job that requires the following:

  • Fully remote work and team. I will be moving to somewhere in Latin America in 2024 or later.
  • Part-time employment. I currently work Mondays through Thursdays, and it greatly benefits my well-being and the quality of my work.
  • Nothing stupid like cars, bitcoin, or advertising.

Relevant job experience

  • Since September 2019: Backend Developer at ioki GmbH, Frankfurt.
    We work with Ruby on Rails, PostgreSQL, PostGIS, and all the other fun standard stuff. My teammates are incredibly skilled, and I am learning a ton from them. Sometimes I can teach them as well. While it's not hard coding-wise, I have the most fun translating public transport pricing systems into human- and machine-readable code. And writing tests of course.

    I host our internal series of tech-focused lightning talks.

  • May 2018 - Aug 2019: Software Developer Ruby on Rails at CHI Deutschland Cargo Handling GmbH, Frankfurt.
    Looking for a job in the Rhein-Main-Neckar area, I overlooked the requirement for Ruby skills in one job ad. Daniel Loy hired me anyways and thus jumpstarted my career as a Rails developer. We now work together at ioki, so everything worked out fine.

  • Jan 2017 - Dec 2017: Software Developer Python at, Mexico City.
    After teaching myself the basics of web development using Python in the previous year, I got the opportunity to build the prototype for a SaaS startup from the ground up. I used Django as the framework, pythonanywhere for hosting, LaTeX for templating and typesetting documents, and I fell in love with pytest.

    This was a super interesting collaboration between lawyers, designers, and me as the developer. While the product never went anywhere, you can still find the designs in my friend Angélica Ramos's portfolio.

  • Sep 2013 - Jul 2014: Bartender at the Ganter brewery experience, Freiburg.
    Learned to draw the perfect beer.


  • 2002 - 2008: Studied physics in Freiburg and Trondheim.
    Diplom / M.Sc. in physics.
