During April 2025, Cheatmaster114 focused on improving the reliability of PostgreSQL backups in the cozystack/cozystack repository. They addressed a bug in the backup cronjob configuration by removing a duplicated template entry and correcting the restart policy, ensuring that backup jobs restart consistently after failures. Working primarily with Kubernetes and YAML, Cheatmaster114 also updated the Helm chart version and versions map to lock in these changes, reducing the risk of duplicate or missed backups. This targeted engineering effort enhanced data protection and operational stability, demonstrating a strong grasp of DevOps practices and attention to detail in production infrastructure maintenance.
