Fintech & Risk Advisor — Ex-Facebook & PayPal

Fractional product leadership, payments systems design, and fraud/risk strategy for fintechs & marketplaces

I help early- and growth-stage companies scale payments, reduce fraud losses, and ship resilient product systems. I combine product leadership, payments operations, and data-driven risk strategies to turn recurring operational losses into predictable growth.
