Hi, I'm Jan — HTL Leonding graduate, open to work. I build AI infrastructure: MCP servers, retrieval pipelines and developer tooling — backend-first, from embedding evaluation down to Raspberry-Pi deployment.
→ Explore the portfolio for case studies, projects and the full skill matrix.
MCP server exposing school-internal LeoWiki (DokuWiki) to AI clients via OAuth 2.1 + RBAC — always-on on a Raspberry Pi 5.
17× retrieval improvement (MRR 0.051 → 0.883) · German-optimized embeddings, five-stage offline RAG pipeline.
