About this gig

Hey, I'm Jann, a professional software developer based in Berlin, Germany. I build custom PHP web applications and help businesses maintain and improve existing software. We can discuss your project in German or English, whichever you prefer.


Need to fix an issue, extend an existing application or turn an idea into a working product? I'll review your requirements and technical setup to find a suitable approach.


What I can do for you:

  • Diagnose and fix PHP bugs
  • Add features and improve business workflows
  • Build dashboards, admin panels and booking systems
  • Develop custom PHP web applications from scratch
  • Help with databases, hosting, deployment and infrastructure


I work with PHP, SQL databases and modern frontend tools. For existing projects, I'll assess the code and dependencies before recommending changes.


You can expect maintainable code, clear communication, the source code and an explanation of the delivered work.


Please message me before ordering. We'll discuss your requirements and agree on the scope, price and delivery time in a custom offer.
