The Hackathon Mobile Wep App provides a real-world solution to Kennesaw State University's College of Computing and Software Engineering's Hackathon event that occurs multiple times a year. Previously, the college was using multiple platforms to bring event registration and collaboration together to make the event a success, placing a large amount of manual work on the administrators who manage the event. The Hackathon Mobile Web App provides a central platform in which students can create an account for and register for the Hackathon event to be placed on teams with sponsors, allowing them to log in to manage their registrations and accounts independently. At the same time, registered administrators have full access to the same platform from an "administrator view" to manage all aspects of the event in terms of getting, adding, updating, and deleting pertinent information, making this solution invaluable in terms of automating many tasks and easing the workload of the administrators in charge of the event.
