Worked on the IBM-Cloud/terraform-provider-ibm repository to enhance security and key management documentation for cloud infrastructure. Focused on clarifying the RFC 3339 format for the expiration_date field in IBM KMS key resources, providing detailed lifecycle guidance to help users avoid misconfigurations and strengthen encryption practices. Improved documentation around key states and recommended actions during data encryption lifecycle transitions, aiming to prevent data exposure risks. All updates were delivered as non-breaking documentation changes, ensuring stable provider behavior without altering runtime APIs. Utilized Go and Markdown to deliver clear, actionable guidance for IAM and cloud infrastructure users managing encryption keys in production environments.
