Worked on the ublue-os/bluefin repository to enhance rollback functionality by introducing NVIDIA Open image variant support within the rollback helper. Focused on expanding user options during system recovery, the work addressed a gap in the rollback process by integrating new image variants, allowing for more flexible and reliable rollback scenarios. Leveraged shell scripting and system administration skills, primarily using bash, to ensure consistent handling of image variants throughout the rollback workflow. This targeted feature improved the overall user experience by broadening recovery choices and strengthening the reliability of the rollback path for systems utilizing NVIDIA Open image variants.
