What I work with

Skills

From the model layer down to the infrastructure that runs it in production.

LLM & Agentic AI

Agent orchestration and tool use: Just-In-Time tool discovery over the Model Context Protocol (MCP), RAG pipelines with chunking and reranking, semantic tool retrieval with embeddings, plus guardrails and fallback chains that keep agents predictable.

LLM Evaluation & Monitoring

Tracing multi-step agent conversations with Langfuse and OpenTelemetry, LLM-as-a-Judge evaluation that checks tool selection and output validity, and prompt engineering for cost and reliability in production.

AI Engineer
01.2026 – Present
Frankfurt am Main, DE · Hybrid
  • Working on an enterprise AI project that automates business workflows using LLM agents.
  • Built a Just-In-Time (JIT) tool discovery system with the Model Context Protocol (MCP), so agents find and call the right API at runtime based on the user request.
  • Added tracing and monitoring with Langfuse and OpenTelemetry to follow multi-step agent conversations and debug them in production.
  • Built an LLM-as-a-Judge evaluation setup that checks whether agents pick the right tools and return valid output.
  • Added fallback chains and input/output guardrails to keep agent behaviour predictable and safe.
  • Improved tool retrieval speed and relevance using ChromaDB and embeddings.
