Worked on security hardening and maintainability for the IBM/storage-fusion repository, focusing on Kubernetes RBAC improvements. Introduced a custom ServiceAccount for the acl-checker, replacing the default configuration to enforce least-privilege access and enhance auditability. Updated YAML definitions for roles and role bindings, providing clearer documentation and easing onboarding for operators. The work centered on strengthening security posture without addressing bug fixes, emphasizing proactive risk reduction and operational clarity. Leveraged skills in Kubernetes, RBAC, and YAML configuration management to deliver these enhancements. The changes improved both the technical robustness and the maintainability of access controls within the project’s infrastructure.
