What I do
Product & data, end to end.
For a decade I've shipped software. For seven years I've led FinTech products at Braintree, PayPal, Venmo, Xoom, and Mastercard — from payment APIs to dispute automation to internal tooling that the risk and compliance orgs rely on every day.
Today I split time between senior PM consulting and a PhD at Galileo University, researching Retrieval-Augmented Generation, Text-to-SQL, and access to Open Government Data.
