Horse Racing Game Website Completion

We are seeking an experienced web developer to create an interactive and engaging website for a points-based horse racing game. The primary objective is to provide users with a platform where they can participate in a scoring system by predicting the outcomes of horse races. Key expected features include: User registration and profile management; a robust system for point allocation and tracking; dynamic leaderboards; integration of horse racing data (source to be defined); an intuitive user interface and responsive design for both mobile and desktop devices; and an administration panel for managing users, races, and game rules. The project requires a complete solution, ranging from UI/UX design to backend development and database implementation. Experience in game development or interactive platforms will be highly valued, as will the ability to propose innovative solutions that enhance the user experience. The freelancer is expected to deliver a fully functional and optimized final product.
