April 2025: Upgraded upgrade lifecycle reliability across canonical/k8s-snap and canonical/cluster-api-k8s with a new centralized framework and robust testing, delivering business value through non-blocking upgrades, improved governance, and faster recovery from failures.

March 2025 was focused on extending test coverage, hardening upgrade paths, and improving release governance across three repositories. Key features include Ceph integration tests in the k8s-operator nightly CI (GitHub Actions matrix, Terraform deployment tweaks, new Ceph manifest, and environment handling refactor). In k8s-snap, airgapped CK8s testing framework with isolation broadened test coverage for proxy-internet and private registry scenarios, along with reliable upgrade hooks for k8sd. Additional CI improvements added Mattermost notifications, stricter nightly criteria, robust test-result handling, and stabilization of TICS workflows for better visibility. For cluster-api-k8s, 0.4 release versioning and metadata alignment were completed. These efforts collectively increased test coverage and reliability, reduced flaky behavior in upgrades, and improved release traceability, delivering measurable business value by accelerating feedback cycles, reducing risk in upgrades, and improving release quality. Technologies demonstrated include GitHub Actions, Terraform, Ceph deployment tooling, CK8s, LXD, xdelta3, and Mattermost CI integrations.

February 2025 focused on stabilizing release pipelines, simplifying configuration checks, and improving test visibility across the Canonical Kubernetes Snap projects. Delivered targeted features and fixes that reduce operational risk, accelerate feedback, and enable more reliable deployments in Kubernetes Snap environments. Demonstrated proficiency in Kubernetes operations, CI/CD automation, and infrastructure-as-code practices.
