Freelancer profile translated to English.

Description

I develop software that runs – and infrastructure that lasts.

My background combines computer science studies (B.Sc., University of Münster) with over a decade of practical experience in the technical field.

Software development for me means: complete cycles. From requirements analysis through clean, documented implementation to the delivered product – with version control, automated tests, and handover documentation.

I use modern AI tools (Claude, GitHub Copilot) as a productive part of daily development – as a lever, not a substitute for technical understanding.

See my work for yourself at: Programming languages: Java · JavaScript · Python · C/C++ · Haskell

Web & Databases: HTML5 · CSS3 · Canvas API · MySQL

Tools & Infrastructure: Git · Docker · Ubuntu Server · Raspberry Pi · Nextcloud · Fusion 360

Whether for a short-term contract, a longer-term project collaboration, or an existing project for further development – I look forward to an initial conversation.
