Broox Integration is a containerized set of scheduled and manually run Python scripts that I use to manage the data that powers the Broox API. Its primary purpose is to sync data with various social networks (Flickr, Twitter, Foursquare), but I also use it for things like moving photo assets to cloud storage providers or running batch operations on my local data. All third party API response data that I fetch is cached in a Mongo DB and then manipulated to store only the relevant data in the MySQL DB that powers the Broox API.

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.

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.

Venmo Payouts is a product that I got to build as a proof of concept and then turn into a full-fledged product alongside a small team of developers. The initial proof of concept was a shotgun hack to power a couple marketing campaigns that would allow merchants like Chipotle to send small payments to users in an effort to get them to buy burritos. After the success of the pilot campaigns, I acted as a tech lead and liaison between the Venmo team and PayPal MassPay teams to architect and build out a highly scalable merchant-to-consumer payout platform. I designed the APIs, data stores, and contracts between PayPal and Venmo.

The Venmo Debit card is a physical card that Venmo users can request to make purchases with their Venmo balance. This was one of the first products that we offered that would allow users to do more than just peer-to-peer payments with their Venmo wallet. I developed APIs and data stores related to storing sensitive user information including the federally required Customer Identification Program (CIP) user information. I also worked on various other debit card servicing APIs like the card design picker and card renewal.
