I design and build agent systems that hold up in production - orchestration (LangGraph, Claude Code SDK), tool design, state management, human-in-the-loop, retries and guardrails. You get a working system, the agent/tool definitions, and handoff docs. Ongoing engagement: ~$3,000/mo part-time (10 hrs/wk) or ~$5,500/mo dedicated (20 hrs/wk). We can start with a 1–2 week initial build so you see real output before committing.
