About

Operations into systems, with people in the loop.

I'm a founder and technologist with 10+ years turning operational problems into automated systems: real-time sensor monitoring for a major airport project, apps and e-commerce for small businesses, and now an ERP for flexible-packaging manufacturers with an agent layer built on Claude.

I design agentic workflows with human-in-the-loop approvals, permission scoping and cost guardrails, and ship them to real users on the plant floor and in the back office.
