Hi, I am Friedrich 👋

I build software for European startups and SMEs.

I'm a freelance software developer and consultant. I work with companies that need custom software, web applications, or an experienced engineer to think through architecture with them.

My focus is privacy-first engineering: systems that run lean, keep data where it belongs, and stay understandable after I hand them over. If you're planning something, get in touch.

Available for new projects

Services

Things I do, from a one-week review to a long-running build.

Custom software development

Backends, internal tools and data pipelines — designed, built and documented end to end.

AI workflows

Practical AI for companies — from a first pilot to internal assistants that automate repetitive work, with your data kept under your control.

Technical consulting

Architecture reviews, technology selection and feasibility work — short engagements, clear recommendations.

Privacy & data sovereignty

GDPR-aware design, self-hosted infrastructure and data flows you can actually explain to a lawyer.

APIs & integrations

Connecting the systems you already run — clean interfaces instead of manual copy-paste work.

Something else?

If it's software and it's tricky, it's probably a fit. Tell me about it.

How I work

Three things clients tend to notice.

Contact

The quickest way to start is a short email: what you're building, the rough timeline, and whether you already have a team in place. I answer personally.
