Coca-Cola Mix'On was a promotional campaign centered on a musical collaboration and competition among three Latin musical artists, with the winner determined by public voting and awarded a performance slot at the American Music Awards. The project was a consulting engagement with LBi, a New York-based digital agency handling the Coca-Cola promotional account.
The front-end was built using HTML, CSS, jQuery, and LESS, with Twitter Bootstrap providing the responsive grid and component base. AJAX was used extensively throughout the voting and content interaction flows, enabling dynamic content updates without full page reloads — an important consideration for a voting-driven promotion where user engagement and immediate feedback are central to the experience.
A custom RESTful API served as the integration layer between the front end and the back-end vote processing system. The back end was built on CakePHP by the LBi team and handled vote counting, fraud prevention, result tallying, and data management for the competition. The front-end consumed this API to submit votes, retrieve current standings, and display real-time results to users — a data-driven interaction model that required careful coordination between front-end request handling and the API contract defined by the back-end team.
Latin music promotions at this scale involve significant traffic during peak voting periods and require front-end implementations that handle concurrent API calls without degrading the user experience.
