My approach

Software is never an end in itself for me.

I am interested in the problem behind a requirement: Where does information get lost? Why does a process keep consuming time? Which structure is missing for a process to scale reliably?

I combine full-stack development with process insight, data integration and practical DevOps. The result is maintainable software that genuinely makes people’s work easier.

01

Open & transparent

Open source, self-hosting and clear data models are building blocks of digital sovereignty for me.

02

Pragmatically automated

I automate where it reduces long-term effort, prevents errors and improves everyday work.

03

AI with a system

I combine local models, OCR and rules into robust workflows – using AI where it provides genuine value.
