I am very happy working at ioki at the moment.

But in 2024 or later I will be moving to Latin America with my wife, who will be working at a German school there, and that will require me to have a job that allows me to work

  • fully remotely, and
  • from a different timezone (UTC-3 to UTC-5).

Additionally I prefer:

  • Part-time employment. Currently I work Mondays through Thursdays, and it greatly benefits my well-being and the quality of my work.
  • Not working on stupid things like cars, bitcoin, or advertising.

I am not a computer scientist. I am a physicist by training and a musician by passion. But I've been working with computers my whole life. I wrote my first HTML in the 90s and started developing websites professionally with WordPress around 2010.

2016, while living in Mexico, I finally picked up Python and Django in order to develop more serious web applications. I got my first paid project in 2017 and have been working in the field ever since.

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 and my lead Andreas Schwarzkopf 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.

    Proudest achievement: I successfully replaced Jira with GitHub issues for the team's task management.

  • 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.

    Coolest story to tell: How I tested the LaTeX templates for legal documents using pytest.

  • 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.
