Tech Trader is a mobile web app that provides, for the students of Georgia Tech, a platform to buy/sell goods/services on campus. The UI was created using the GT-Mob framework for widgets. The framework handles the styling of the widget using jQuery Mobile. User authentication is done by the framework using Georgia Tech's Central Authenticating System (CAS). Once the user is authenticated, he/she can browse through the listings to find the required products. The listings are organized into seven categories: books, furniture, electronics, service, events, lost & found and miscellaneous. Every category page is also equipped with a dynamic search filter to optimize usability on mobile devices where the real estate of the screen is restricted. The sell page allows students to add a product to the listings by specifying its title, description, price and category. Each listing provides information about the product and a link to contact the seller. The communication takes place through Georgia Tech email.
