About Jan

Ich bin Mobile Developer, Technik-Enthusiast und Innovator mit einer großen Leidenschaft für Software, Technologien, Innovation und Automatisierung. Während meiner bisherigen Projekte habe ich unter anderem bei MixMyMeal Wireframes designt, Backend-Entwicklung betrieben und skalierbare Infrastrukturlösungen erstellt. Dabei setze ich auf moderne Tools wie Next.js, Postgres und Drizzle sowie auf Terraform und Coolify für das Infrastrukturmanagement. Zudem habe ich Authentifizierungssysteme wie OAuth und Magic Link erfolgreich integriert. Vor der Entwicklung mit Webtechnologien habe ich als Werkstudent bei E3DC sehr hardware-nah mit C++ programmiert. Mein Ziel ist es, technische Lösungen zu schaffen, die nicht nur funktionieren, sondern begeistern, und dabei stets kreative Ansätze in jedes Projekt einzubringen.

    Programmer who update 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.

    Osnabrück, NI, Germany
    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.
