Über mich
As a Senior AI Solutions Engineer and Architect, I turn ambiguous operational problems into working AI products across the full lifecycle: discovery, workflow redesign, architecture, hands-on implementation, integration, evaluation, deployment and continuous improvement.

Projekthistorie
Built a publicly accessible multi-agent customer-support engineering showcase with LangGraph, Azure OpenAI and PostgreSQL/pgvector retrieval with source citations. Implemented specialist-agent workflows, AG-UI streaming, A2A collaboration, human handoff/approval and authorization boundaries. Added reproducible evaluation, RAGAS-oriented quality checks, Langfuse observability and automated tests.
Explored Pinecone vector indexing and Neo4j graph-based relationship retrieval in a separate proof-of-concept; not represented as client production deployment.
Design and implement LLM applications, governed agent workflows and RAG solutions with Python, TypeScript, Azure OpenAI and API integrations. Own solution design, security boundaries, integration, evaluation, client demonstrations and technical delivery.
