Software that still makes sense in two years.

Senior-level backend work in C# / .NET Core, with an eye on performance, security and architecture that still scales once the traffic arrives. Where location matters, I bring hands-on GIS experience from building two geodata platforms — map layers, OGC interfaces and the data pipelines behind them. I design the system before I write it, and I write it so the next person can read it.

Fast web frontends with Astro — the kind that load instantly and are easy for search engines and AI assistants to read — and Angular where an application genuinely needs a complex single-page architecture.

Search engines and AI assistants can only rank what they can read. I work on the technical layer underneath: load times and Core Web Vitals, structured data, clean multilingual setups with hreflang, and everything crawlers trip over. The proof is malsati: 250,000 visitors a month, all of them from organic search.

Practical AI, not a demo: integrating LLMs into products that already exist, building RAG pipelines over your own data, and automating the steps nobody should still be doing by hand. Plus IoT where devices need to join the conversation.

Technical leadership without a full-time hire. I advise on technology choices, run code audits that tell you what you actually bought, and tidy up how your team ships. Useful when you need the judgement more often than the headcount.

I’m convinced that European data belongs on European servers, and I actively move applications off US clouds onto European infrastructure — self-hosted with platforms like Coolify. This site runs that way itself, on Hetzner in Nuremberg.
