Venmo Purchase Protection
Purchase Protection provided a simple toggle button for Venmo consumers to specify whether or not they're paying for goods or services while sending a payment. When a payment is sent for goods and services, the seller would be charged a small fee and the payment would automatically be covered under Venmo's Purchase Protection Program. If something went awry with the transaction, both the buyer and seller could be covered and reimbursed.
I was the lead architect for this feature and designed the APIs, data storage and fee collection solutions.
