Worked on the All-Hands-AI/OpenHands repository to enhance the reliability and user experience of the feedback submission process. Introduced retry logic for feedback submissions, ensuring that failed attempts are automatically retried to improve overall reliability. Improved the frontend using React and TypeScript by adding clearer status indicators and more informative error messaging during submission, which helps users understand the process and any issues encountered. Updated the README_CN.md documentation to reflect these changes, supporting easier onboarding and ongoing maintenance. Focused on frontend development and internationalization, the work addressed both technical robustness and usability within a short, targeted development period.
