Current Work — Consulting, Systems, and Product R&D

🔧 Westmark.dev

Consulting + practical product delivery.

Delivery sprints: Workflow-heavy MVPs, UX cleanup, and scoped implementation work.
Applied AI: Agent-assisted workflows used to speed research, implementation, and handoff artifacts.
Client fit: Small SaaS teams, founder-led products, and practical internal tooling.

🧠 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.
