About Jan

I am a Mobile Developer, technology enthusiast, and innovator with a great passion for software, technologies, innovation, and automation. In my previous projects, I have designed wireframes, performed backend development, and created scalable infrastructure solutions for MixMyMeal, among other things. I rely on modern tools such as Next.js, Postgres, and Drizzle, as well as Terraform and Coolify for infrastructure management. I have also successfully integrated authentication systems like OAuth and Magic Link. Before developing with web technologies, I programmed very hardware-close with C++ as a working student at E3DC. My goal is to create technical solutions that not only work but also inspire, while always bringing creative approaches to every project.

    Programmer who updates the already implemented feature
    February 2025 - February 2025 (1 month)
    Celle, Bundesrepublik Deutschland
    My main task was to update and further develop already implemented features. Thanks to a clear code structure and well-documented tasks in GitLab, I was able to work efficiently. The collaboration was mostly asynchronous, with occasional spontaneous clarifications when needed. Overall, it was a very valuable and enjoyable experience.

    Osnabrück, NI, Germany
    I completed a mandatory 10-week internship at Netrocks as part of my Bachelor's degree program in Computer Science and Engineering at Hochschule Osnabrueck. Following this, I wrote my bachelor thesis, which focused on building a white-label frontend solution with Flutter, using an existing backend implementation.

    My first task involved moving files/folders with a specific pattern in SVN from one location to another, for which I wrote a Python script. I also developed a testing package for the embedded system. The developer can run the debugger on their machine but still use the IO of the real device.
