Student Dashboard and Social Network for Major University

I worked with a Toptal client to produce a student-facing website to help students excel in their Business Master's degree. The project involved multiple iterations, continuously received new features, and was eventually relaunched for another degree.

The website was powered by WordPress, a handful of plugins, and was heavily customized. It is integrated directly with the university's single sign-on (SSO) system.

The main features of the website:
Students were able to earn points by completing online and offline activities.
• Students could redeem earned points in exchange for university merchandise.
• Students could interact with other students through friend requests, groups, and private messaging.
• University staff were able to bulk import data into the site.
