Closed Loop

Hire me

I take remote freelance engagements building production AI systems. Everything I sell is something I already run myself — the articles on this site are the evidence.

Agentic system design & build

Autonomous task loops, multi-agent pipelines, and background workers that produce reviewed, evidenced output — not chat transcripts. Designed with hard gates, verification baselines, and human-in-the-loop control surfaces.

Evidence: Folders Are States — an autonomous dev loop on Claude Code

Claude Code enablement for teams

Get an engineering team from chat-window usage to structured agentic workflows: skills, subagents, review separation, CI-safe verification, and the operating rules that keep autonomous coding safe on a production codebase.

Evidence: the verification and separation-of-duties patterns in the writing here.

AI infrastructure consulting

Architecture and delivery for LLM-backed products: RAG pipelines, evaluation harnesses, cloud AI services, and the unglamorous plumbing — cost control, observability, and failure handling — that makes them production-grade.

Evidence: production delivery pedigree in regulated iGaming, plus the systems documented here.
