Role and responsibilities

I was a Web Engineer Intern in the Web Core Team. The Lead Engineer for this team is Billy Wai at the time. This team is the main team of the web platform as they’re responsible for the web platform by creating or suggesting new solutions of improvement, constituting best practices to be implemented, and upgrading packages and bug fixes. We also occasionally help build and maintain sub systems in the web app if those don’t fall under the responsibility of the other Web Product teams (also known as pods). Our team is responsible for maintaining three particular systems, the Web App, the Internal Web Design System and the Gateway API. I usually contribute to the Web App the most and a bit to the Design System.
