Worked on the ucl-isd/moodle-mod_coursework repository, delivering enhancements to the Moodle Coursework module over three months. Focused on UI modernization, moderation workflow improvements, and feedback system refactoring, the work included migrating legacy JavaScript to AMD modules with jQuery for maintainability and Moodle 4.5 compatibility. Addressed frontend inconsistencies, updated CI workflows to PostgreSQL 14, and introduced automated Behat tests to ensure stability and regression protection. Leveraged JavaScript, PHP, and YAML to implement new moderation features, improve validation, and enhance reporting accuracy, resulting in a more reliable, maintainable, and user-friendly experience for both administrators and end users.
