Worked on the refly-ai/refly repository to enhance the stability of the image upload workflow by addressing a bug that allowed duplicate uploads. Refactored the image upload component using React and Ant Design, focusing on simplifying the import process by removing drag-and-drop handling logic and associated state. This approach reduced UI complexity and eliminated redundant event handlers, resulting in a more maintainable and reliable upload path. The changes, implemented in TypeScript and JavaScript, made the component easier to test and less prone to edge cases, ultimately improving the overall user experience without introducing new features during the development period.
