Developed and deployed an automated repository synchronization workflow for OpenList-Frontend, enabling seamless mirroring between GitHub and Gitee. The solution leveraged GitHub Actions and YAML to establish secure, cross-platform synchronization, utilizing environment variables and secrets to protect credentials. The initial implementation was refined into a robust single-commit synchronization process, incorporating SSH and known-hosts configuration to enhance security and reliability. This automation reduced manual intervention, minimized drift between repositories, and improved release velocity. The work focused on CI/CD best practices and repository mirroring, delivering a maintainable and secure workflow that streamlines codebase management across multiple platforms without introducing new bugs.
