About Me

"The Best Developer in The World" - based on my wife's ranking

I'm an AI Architect. I design and ship AI systems that hold up in production โ€” not demos. My work sits where the hard problems live: agentic systems at scale, agent and LLM evaluation, AI compliance and governance, and fine-tuning models for real workflows with real accountability.

I think about AI the way an architect thinks about a building: what happens under load, what fails safely, what can be measured, and who owns it a year from now. That means multi-agent orchestration you can actually reason about, evaluation harnesses that catch regressions before users do, guardrails and policy baked into the system rather than bolted on, and fine-tuned models measured against clear baselines.

I build on the Model Context Protocol (MCP) to connect agents to tools, data, and systems securely โ€” and I've spent years proving that JavaScript/TypeScript is a first-class language for serious AI engineering, not just Python. Two decades of large-scale frontend and platform architecture is what lets me ship these systems end to end.

What I architect:

  • Agentic Systems at Scale โ€” multi-agent orchestration, planning, tool use, memory, and failure recovery
  • Agent & LLM Evaluation โ€” eval harnesses, LLM-as-judge, regression suites, offline + online scoring
  • AI Compliance & Governance โ€” guardrails, policy, auditability, safety, and responsible-AI controls
  • LLM Fine-Tuning โ€” dataset curation, training, and rigorous before/after evaluation
  • RAG & Knowledge Systems โ€” retrieval pipelines, GraphRAG, and grounding at scale
  • MCP & AI Tooling โ€” secure, observable connections between agents and real systems

I believe:

  • If you can't evaluate it, you can't ship it โ€” evals are the architecture, not an afterthought
  • Compliance and safety are design constraints, not paperwork
  • Agentic systems live or die on observability and graceful failure
  • JavaScript/TypeScript is a first-class language for AI, not just Python
  • Good architecture is what makes AI reliable, scalable, and accountable

What I'm Working On

Agentic AI, Evaluated and Governed

Current Focus:

  • Agentic Systems at Scale โ€” orchestration, planning, and memory for multi-agent workflows that stay reliable under load
  • Agent & LLM Evaluation โ€” building eval harnesses, LLM-as-judge scoring, and regression suites that gate releases
  • AI Compliance & Governance โ€” guardrails, audit trails, and responsible-AI controls as first-class architecture
  • LLM Fine-Tuning โ€” dataset curation, training, and disciplined before/after evaluation
  • GraphRAG & Knowledge Systems โ€” retrieval and grounding that survive scale and change
  • MCP Tooling โ€” secure, observable ways for agents to reach real systems

Recently Published:

Technical Depth:

  • Evaluation-first delivery โ€” treating evals and observability as the backbone of every AI system
  • AI in TypeScript/Node โ€” proving JS is a serious platform for agents, RAG, and tooling
  • On-Device & Hybrid AI โ€” Chrome Built-In AI APIs and local inference

Impact:

  • Speaking โ€” practical lessons on agents, evaluation, and AI safety at conferences worldwide
  • Writing โ€” articles on agentic AI, MCP, and evaluation on Medium and ITNEXT
  • Community โ€” helping engineers build AI that's measurable, safe, and production-ready
