Amidst the start of the COVID-19 pandemic, the Chicago Venmo team was tasked with launching one of our most ambitious products. We worked closely with PayPal Credit, Synchrony Bank, and several internal Venmo teams to launch a branded Venmo Credit Card product in just 10 months time. I served as a tech lead and cross-company liaison to help architect and lead the development of the Credit Card servicing portion of the product. This included the data syncing, data structures, and API design to power the interfaces that a user sees when viewing or managing any information about their credit card in the Venmo Application. Later, I worked with a small team to add Cryptocurrency Reward functionality and also led the effort to get the Credit Card service's codebase upgraded to a more modern version of Python.
