While at edX, I worked alongside the E-Commerce & Growth team to build and maintain the company's marketing site and checkout flow. While the majority of tasks I performed were maintenance tasks, towards the end of the my time at edX I spearheaded development of a course admininistrative interface course creators could use to manage their courses published on the edX platform (seen below). I also assisted the design team in modularizing their UI design system and moving it to Bower.
