Worked on the percona/percona-server repository to improve upgrade reliability for Fedora 42 users by addressing a migration conflict encountered during MariaDB to MySQL 9.3.0 transitions. Delivered a targeted bug fix that introduced an Obsoletes tag for mariadb-client-utils within the RPM specfile, ensuring a clean upgrade path and preventing package conflicts. This solution leveraged skills in database migration, RPM packaging, and dependency management, with changes tracked and verified using Git. The work reduced upgrade failures and downtime, streamlining major version migrations and enhancing system stability for Percona Server users, while also decreasing support overhead and improving overall user satisfaction.
