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.

The Venmo Credit Card offers up to 3% cash back on a user's top expenditures. After Venmo launched the ability for users to buy and hold cryptocurrency in their accounts, we decided to allow Credit Card users to automatically turn their cash back rewards into the cryptocurrency of their choice. I co-led the effort and worked with a small team of engineers to architect and build the new functionality that made heavy use of Cloudevents, PayPal's crypto APIs, and internal Venmo services to get the job done.

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.

The Modest Control Panel was a multi-tenant Content Management System that allowed merchants to manage their Modest powered storefronts. Features included the management of store themes, payment gateways, shipping methods, orders, third party e-commerce product syncing, and even generating standalone iOS applications. The back-end of this app was built in Python using the Flask framework. The front-end was initially built with plain Javascript and jQuery, but was eventually migrated to React. As the Modest client application tech lead, I oversaw and greatly contributed to the overall product architecture and implementation of this web application.

TowRate was a startup that offered a custom service to towing companies. The site allowed subscribed companies to manage their assets, map routes, and calculate profit margins for every tow. It was built in a way that allowed the towing companies to quickly run these calculations while on the phone, so they could figure out the most profitable way to charge for each tow. On this project, I was in charge of pretty much everything except for the initial design. My job involved data modeling, loads of calculations, back-end development, front-end development, form design, and deployment. TowRate was a very javascript heavy application, using plenty of asynchronous calls for things like sorting, calculating rates on the fly, and grabbing map data from the Google Maps API. The Maps API was used to help determine mileage and time for each tow. From there, the app used extensive math and formulas to help find the best price for each call. Companies were able subscribe to TowRate on a monthly or yearly basis. I integrated PayPal's Web Payments Pro to handle these subscriptions; let users join, autorenew, enter discount codes, cancel accounts, etc. Subscribed companies could also manage their trucks (as well as truck expenses), users, tow rates, tax areas, routes, etc. It provided an all around fleet management solution to any towing company.

Edwards Graphics Arts (a partner to NAPA) hired our company to build a web application for distributing posters and flyers to NAPA's retail stores. Each store could purchase any of several different promotional products. This is a process that NAPA and it's 3rd party designers had previously handled over the phone. I built a web application to help streamline this process and eliminate phone ordering. This app allowed Edwards Graphic Arts to upload and edit designs for the stores to order. Retail store managers could then visit the site and order promotional products that fit their demographic. This site was very javascript heavy with a lot of asynchronous calls to provide a quick user experience. I also integrated it with PayPal's Pay Flow Pro to allow for online payment.

SolidGrind is a personal project that I developed as an extreme sports / soap shoes promotional and community website. It's the predecessor of my former Broox Extreme (www.broox.com) and BrooksFSW community sites. After I came up with the name and domain, I decided that rather than customizing a prebuilt system, I wanted to build this site from scratch. Developing the entire site myself was another great learning experience and paid off numerous times; I had full control and a great understanding of the system, so I could easily add on, fix bugs, and rebuild sections. One of the more fun parts of SolidGrind was the "feature pic" system. It allowed users to upload photos to be reviewed by the administrators that I'd hired. The uploaded photos were queued in a database and could be viewed/approved by administrators. Upon approval, the website would automatically size/scale the image, add a SolidGrind.com watermark to it, create a thumbnail, store it in the database, and feature the picture on the homepage until a new photo was chosen. In addition, I designed it so that each picture had to be featured for at least 24 hours; this gave everyone a fair amount of time on our front page. Besides photos, the site featured news, forums, tutorials, videos, and several other things related to extreme sports.

Wireless Wallpapers was a personal project of mine. It was a site that allowed users to download wallpapers for their early 2000s color screened mobile phones. At the time there were several sites offering this service however nearly all of them only supported one type of phone or charged money for each wallpaper downloaded (usually $1.00 per wallpaper). Wireless Wallpapers allowed users to download unlimited wallpapers for free, which were available for several types of phones. The free wallpapers had a tiny "wirelesswallpapers" watermarks near the bottom of the image, however if the user paid a small fee each month, they could get more features (such as private wallpapers) and the watermark was removed. In addition to this, I added functionality to allow users to upload their own images to the website which gave me the ability to let the site run itself. The website automatically resized the uploaded user images to fit various mobile screen sizes and printed my watermark to the image. The site was a huge success and learning experience. The first day it was online it received 7,000 hits and had nearly 100 users. After the first week there were nearly 50,000 hits and 500 users. Upon selling the site, I had over 24,000 users and received over 3,200,000 hits.
