Current Work — AI Workflows, Systems, and Product R&D

Claude/API Workflow Systems

Agent-assisted delivery with human review.

  • Forage: Repo-local work-item management for research, design, build, and publish flows.
  • Job-search agents: Claude-powered discovery, scoring, and follow-up pipeline.
  • Operating constraint: AI speeds execution, but artifacts and decisions stay reviewable.

IQue

Internal runtime for delivery and replay.

  • Queue-first runtime: Boutiques, routing, and operator-friendly task flow.
  • Replay model: Agent memory, deterministic reruns, and time-travel debugging.
  • Use case: Internal delivery system that improves consulting output without becoming client-facing overhead.
