A custom component built for SellX allows sales representatives to dial clients by queuing them up and auto dialing instead of clicking through each one individually. To do this, the client dials into a Twilio conference call, then individually dials the numbers it is supposed to, and auto hangs up if it detects a voicemail. There are settings to speed up or slow down the process and turn on and off the voicemail detection. WebSocket is used to pass live information back and forth, so the dialer is in sync with what is going on as it is happening. The list of clients is automatically generated by aggregating all tasks due for that specific day and organizing them into groups of calls. Overall it is a very complex piece of software that is part of a bigger marketplace but increases representatives' ability to dial calls at two to three times the normal speed.

A client that owned a PSL—season tickets for the NFL—ticketing resale and management site wanted to upgrade their site to manage it themselves. It required building a custom seat map that the client could use for stadiums so the customers could select sections and get direct views of their seats from their respective locations.

I designed and built admin management and client-facing components in D3.js, allowing the company to build their own stadiums and save them. On the client-facing side, it would render that stadium and allow them to select a section to filter the results based on the section.

It was an enjoyable project to build, test, and search for tickets based on a map instead of typing and filling in random filters.

This company was initially responsible for testing and serving Adblock messages for publishing companies such as CNN. The message "Please turn off your adblocker" will be shown when going to the site with AdBlock on. The client quickly found this was an uphill battle as AdBlock constantly updated to get around these messages. They decided to pivot to cookie and privacy management, but their messaging system was not built to handle that input.

I designed and built a custom messaging system that lets companies shape, color, label, and change settings to create any message they want and display it on their site given specific triggers. I built it using React for the builder and Vanilla JS for the script to determine what message to show and how to store the data. Since it worked great, I could even take on the AdBlock messaging from the previous system and put it in our new messaging system and other new ones such as email subscriptions and privacy request forms (CCPA). At its peak, the custom white-labeled messages were pulled one billion times per month.
