What I build
Five focused practices. Each page answers a different buyer question — architecture, timelines, safeguards, and what production-ready actually means.
AI Agent Development

Why teams hire me for production AI
- Human-in-the-loop by default — agents propose, people approve, for any action that touches money, customers, or records.
- Observability and replay — every agent decision is traceable; incidents are debugged from logs, not guesswork.
- Cost controls in code — per-run token budgets, model routing, and caching, so the invoice never surprises anyone.
- Evaluation before release — retrieval quality and answer-grounding measured on every change, not vibes.
