JooMaths is a large-scale French e-learning platform designed for students up to the 10th grade, and I developed a fully custom WordPress theme to power the entire system. The platform includes dedicated dashboards for teachers, students, parents, and administrators, each with tailored tools, permissions, and workflows to support learning, course management, performance tracking, and communication. I engineered complex data structures by creating multiple custom database tables directly through theme functions, ensuring smooth data flow across courses, lessons, assignments, progress metrics, and user roles. The custom theme was built to handle high volumes of content and interactions efficiently while delivering a modern, intuitive interface for all user types. This project demonstrates my ability to architect and develop a complete, scalable LMS solution within WordPress using custom code, advanced role management, and optimized backend structures.
