About

Solid engineering, honest advice

With over 15 years of experience, from a technical apprenticeship to applied computer science at the University of Salzburg and my own products. My focus is business software, ERP integration (Odoo is my specialty) and automation. I develop GDPR-compliant and can host your solution in the EU or on your premises, so your data stays with you.

Software is craft

Good software comes from experience and care, not from the next buzzword.

AI stays a tool

In most projects AI is only a small part. The bulk is solid engineering. That is what I deliver.

No lock-in

You get the full source code and stay in control. No opaque platforms, no dependency.

Long-term partnership

I build your product and stay by your side: one point of contact who knows, maintains and evolves it with you over the years.
