Product decisions are
business decisions.
Head of Product with 7+ years in healthtech and fintech, 3 of them applying AI to products and workflows. I connect every product investment to revenue, margin, and operational leverage: 425% revenue growth with 30% headcount increase in the last cycle.
About
Background

Most of my career has been in domains where the gap between clinical or financial workflows and the product that supports them determines whether the business scales or breaks. I spent nearly five years in fintech building collections CRMs, self-service payment flows, and orchestration platforms that tripled agent productivity. Then moved to healthtech, where I applied AI to clinical and operational workflows and led product through a period of rapid growth.
What I care about: making sure every product initiative ties back to a number that matters to the business. Not vanity metrics, not feature counts. Revenue, gross margin, cost per operation, time to value. I work alongside clinical, operations, and engineering leaders to find where product can create compounding leverage.

Let's talk
I am looking for Product roles where the product team owns outcomes, not just output. If your business has operational depth and you need someone who applies AI to core workflows and ties product work to the P&L, I would like to hear about it.
