About

I build applied AI systems that connect LLM capabilities to reliable products. At RWTH IT Center, I work on a multi-tenant AI platform spanning model APIs, streaming, usage and cost metering, and backend operations.

I also investigate deployment and authentication failures, validate provider behavior, and work through web-search and RAG integration requirements. This combines C#/.NET engineering with ML experience.
