Worked on maintaining and stabilizing the candys-shop repository, focusing on codebase integrity and risk mitigation rather than feature development. Addressed two critical issues by reverting unintended binary file uploads and rolling back an incorrect metadata fix for Super Mario Bros. 3, ensuring the repository remained free of unnecessary artifacts and regressions. Employed disciplined version control practices using Git, with careful documentation to support traceability and auditability. Prioritized data integrity and consistent user experience by restoring prior stable states when necessary. The work demonstrated a methodical approach to repository management, emphasizing stability, rollback procedures, and adherence to best practices in change management.
