Decisions, not dashboards.
I lead healthcare data and AI products from hard problem to operating system: products people trust, buy, and use to make a decision.
The hard part comes after the chart loads. I build the structure that carries evidence into an owned decision and a repeatable workflow.
- ClarifyName the decision and the owner.
- GroundTest the claim against real evidence.
- BuildShip the smallest system that can change the call.
- OperateMeasure the outcome and close the loop.
