During June 2026, contributed to the apache/shenyu repository by enhancing both documentation and backend security. Improved the onboarding experience by updating README links, ensuring users could easily access the correct resources and reducing potential confusion. Addressed a security vulnerability in the sandbox proxy by implementing proper closure of HTTP exchanges and restoring utility functions, which mitigated response leaks and improved the reliability of sandbox operations. Validated these changes with comprehensive unit tests, demonstrating attention to code quality and CI integration. The work leveraged Java for backend development, with Markdown used for documentation updates and version control practices maintained throughout the process.
