Zainab Amin developed large file upload support for the /upload endpoint in the srbhr/Resume-Matcher repository, enabling users to upload files larger than 2 MB with improved reliability. She approached this by implementing streaming and enhanced file size validation, ensuring robust error handling and clearer failure states for oversized uploads. By removing redundant empty-file checks, she streamlined the upload process and reduced unnecessary overhead. Her work focused on backend development using Python and API design, with careful attention to file handling and code maintainability. Over the month, Zainab delivered a focused, well-structured feature that improved scalability and user experience.
