RL Garage for Rocket League

RL Garage brings the biggest Rocket League trading and car design platform to the user's phone. It provides post-trade offers and connects the user with other players. As the official companion app for rocket-league.com, designed and optimized for mobile, RL Garage is the largest trading platform for Rocket League, with over 5,000,000 registered users.

I am the primary mobile app developer of this project, writing 95% of the code inside it. Along with development, I wrote many API endpoints for interacting with the database and oversaw Node.js apps running on AWS to generate in-game screenshots of Rocket League on command.

As one of the owners, I also interacted with our users daily through our Discord server of over 200,000 members, support ticketing system, and the app or website messaging system.

Cloudflare Worker to Cache API

This project was for RL Garage for Rocket League. Every day at 3 PM EST, we sent a push notification to our users to let them know that the in-game item shop was updated, resulting in a tremendous amount of traffic hitting our back end.

To curb this, I built a Cloudflare Workers on top of our API to cache most affected endpoints to cut the load on servers by a quarter of what it was before. This idea came when I tried to reduce our server load and database crashes and lower our server costs on AWS. The worker is written in JavaScript using Cloudflare Workers cache API.

Conversation Element in Lessonly

https://seismic.com/lessonly/
React app built upon original React on Rails application. The platform was designed for managers and employers to create lesson plans for their employees to perform their job duties better or onboard them for new responsibilities. It is like making PowerPoint presentations but with more powerful tools like progress tracking, quiz taking, and video and audio recording.

My duties on this project varied over time. One of the largest tasks I worked on was introducing a new element type to lessons called conversations. It involved creating a custom test conversation and quizzing the participant on the best responses during the conversation. The target audience for this was customer support agents. I implemented most of the front end for creating and taking this lesson element.

During the implementation of this project, I worked directly with the director of product and engineering to meet the requirements. I also worked with the design team to ensure the product fit well into our latest design guidelines and provided guidance for what was and wasn't possible in our tech.
