  • Built an AI-supported recruiting and company intelligence platform with end-to-end data pipelines from APIs, ATS systems, and web sources.
  • Structured extraction and normalization of large volumes of raw data with provenance, hashing, deduplication, and revalidation. Replay instead of re-fetch: raw data and source states are persisted so that every analysis can be reproduced without another external fetch.
  • RAG, retrieval, and scoring components as well as agentic workflows for research, analysis, and technical execution, including tool and MCP integration.
  • Agentic delivery with separate roles for planning, implementation, review, and merge; states, queues, liveness, credentials, and human gates are technically separated.
  • Quality assurance through CI, independent reviews, counterchecks, regression gates, and human-in-the-loop approvals instead of unchecked agent claims.
  • Own AI and data infrastructure: PostgreSQL, Redis, Weaviate (Vector Search), local model deployment, vLLM/RunPod PoCs, and model/provider routing.

Summary

I design production-ready AI and agent systems: RAG/LLM components, structured data and extraction pipelines, evaluation, regression protection, and human-in-the-loop workflows. My strength is translating complex requirements into system architecture, data flows, state models, guardrails, and measurable acceptance criteria, and leading implementation through to a demonstrably working system.

Working model: I handle architecture, specification, orchestration, and verification. I accelerate implementation through specialized engineering and coding agents with separate roles for planning, implementation, review, and merge.

Background: over 10 years of enterprise delivery, product ownership, and process digitalization in the energy sector (E.ON, IBM iX, EWE), focused on AI systems architecture since 2025.
