Youdemy is an innovative e-learning platform designed to transform the way students and educators interact with online education. The platform offers a comprehensive system that allows users to browse, create, and manage courses, ensuring a highly personalized and interactive learning experience.
This project is a back-end development solution for a modern and interactive e-learning platform. Built with PHP (OOP), the platform provides modularity, clarity, and extensibility. It offers a seamless learning experience for students, teachers, and administrators, with robust features and a clean, scalable architecture.
