Worked on the exelearning/exelearning repository to implement native OpenDocument Format support within the modal file manager, enabling direct handling of ODT, ODS, and ODF files in the user interface. Focused on front end development using JavaScript, the contribution involved updating modalFileManager.js to integrate these formats, streamlining document management and reducing manual steps for users. The approach emphasized maintaining code quality and aligning with existing repository standards, ensuring a smooth integration into the codebase. This feature improved workflow efficiency and laid the foundation for broader file format compatibility, with all work delivered through the established code review process.
