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.

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.
