January 2025: Delivered targeted reliability and documentation improvements across Mirantis/hmc and k0rdent/docs that reduce risk, accelerate incident resolution, and strengthen operator onboarding. In Mirantis/hmc, implemented KCM Template Distribution Gatekeeping: the TemplateChainReconciler now distributes only templates managed by KCM template chains by enforcing the KCM-managed label, with tests updated to reflect the new filtering. This reduces the chance of propagating unmanaged templates into clusters and stabilizes deployment configurations. In k0rdent/docs, documented and provisioned a workaround for a known EKS MachineDeployment preflight failure, adding guidance and an annotation-based remediation to the EKS MachineDeployment object. The documentation now references this known issue to speed up future triage and resolution. Impact: improved deployment reliability, reduced mean time to recovery for known issues, and streamlined onboarding for operators. Technologies/skills demonstrated: Kubernetes controllers and label-based filtering, test updates, YAML annotations, and cross-repo documentation.

December 2024 — Mirantis/hmc: Key progress across access control, cloud provider integration, and reliability. Implemented the Access Management revamp (renaming TemplateManagement to AccessManagement across the codebase, expanding access control scope, and updating CRDs, controllers, webhooks, and tests), plus introduced a credentials distribution system. Delivered AKS infrastructure integration with cluster templates, credential YAMLs, and propagation controls (including a skip-credentials propagation option) via Helm charts for AKS clusters. Fixed a Helm release reconciliation panic by ensuring ReconcileInterval is set only when chartSpec is present, improving runtime stability. These efforts collectively strengthen security, accelerate automated AKS deployments, and reduce deployment-time incidents.
