Megh Bose developed a feature for the GoogleCloudPlatform/magic-modules repository that enables customizable retention periods for on-demand backups by adding the maxCustomOnDemandRetentionDays property to BackupPlan. This work involved updating YAML configuration files, modifying Terraform templates, and implementing automated tests to ensure the new property functioned reliably across the infrastructure. By focusing on backup management and cloud infrastructure, Megh provided users with greater flexibility in defining backup retention policies, supporting improved governance and potential cost optimization. The project demonstrated proficiency in Go, YAML, and Terraform, with the engineering effort centered on robust feature delivery and cross-repository collaboration rather than bug fixes.
