This web application was designed to complement Denny sausages' packaging, where users could find unique codes on their packs from specific stores. Utilizing the Facebook app, users could enter two codes for a chance to win a prize.
Validation played a crucial role in this application to ensure that the entered codes were both valid and unused. Upon saving a form with the correct valid codes, they were immediately marked as 'used', preventing others from utilizing them. To achieve this, I implemented a robust system using AWS RDS and an indexed MySQL table. This setup allowed for rapid detection and real-time feedback to users, confirming whether their codes were accurately inputted or not.
