The Engineer

I build agentic systems that hold up under real traffic.

12+ years in software, 5+ in production AI. Agentic workflows, tool-calling, retrieval pipelines, NL2SQL engines. Judged on eval scores and uptime, not demos.

Earlier years in cybersecurity automation (SIEM, IDS/IPS, SOAR) shape how I design for safety in everything I ship now.

NL2SQL accuracy (SADIE)

Agentic

Production agentic systems

Tool-calling agents with intent routing, multi-turn context, and hallucination grading. Long-horizon harnesses with durable plans and checkpointing.

Retrieval

Hybrid retrieval

Dense + sparse + graph. Qdrant (ModernBERT 768d + BM25, RRF fusion) plus Neo4j graph traversal. Custom rerankers where it pays.

Evals

Evaluation as engineering

RAGAS, LLM-as-judge calibrated to labeled data, CI-gated regression, Langfuse end-to-end. If it isn't measured, it isn't shipped.
