Debarghya developed a Microsoft Graph File Download feature for the Coding-Club-IITG/CourseHub repository, focusing on enabling secure and efficient remote file access. He implemented backend routes and a controller in Node.js and JavaScript to interact with the Microsoft Graph API, generating secure download links and supporting local development server testing. The work emphasized API integration and backend development, laying the groundwork for seamless frontend integration and end-to-end testing. By streamlining content distribution and reducing manual download steps for both developers and instructors, Debarghya’s contribution established a robust, traceable foundation for scalable file delivery without addressing major bug fixes this month.
