As the design PO for CLASS101's first online conference project, I successfully helped attract around 4,000 pre-registrations, with 500 participants attending the live online event. The conference launch has been considered a success, especially as CLASS101's first-ever conference. In my role, I led the design of the pre-registration page, including workflow planning, UX/UI design, Brand design, speaker presentations, and online promotional materials. My top priority was to ensure the design was sustainable for future use. The first conference focused on the development and data category, so I aimed to create a design that was simple and essential, aligning with the tech-oriented theme. Additionally, I designed workflows that encouraged user sign-ups, contributing to the growth of the user base.
