During May 2025, Oopa17 developed the foundational Course Management GUI for the Decr0zeath/Simple-LMS-OOP-Project-2025 repository. Using Java and Swing, Oopa17 established the main project configuration, implemented the primary Java class, and created a navigation skeleton supporting Courses, To Do, and Grades modules. The work included a dynamic placeholder for displaying course subjects, designed to enable future data binding and rapid UI expansion. By setting up the initial repository structure and graphical interface, Oopa17 laid the groundwork for scalable Learning Management System features. The month’s engineering focused on robust GUI development, with no major bugs reported during this period.
