Worked on the RCOSDP/weko repository to enhance the Secret URL Email Template, focusing on improving user clarity and strengthening security instructions. Utilized SQL scripting and database management skills to support these changes, ensuring that the template updates integrated smoothly with existing systems. When issues arose after deployment, promptly executed a rollback to restore the previous template content, demonstrating a careful approach to risk management and system stability. Maintained clear documentation and precise commit messages throughout the process, facilitating collaboration and traceability. The work combined email template design with technical troubleshooting, resulting in a stable and user-focused Secret URL flow.
