Worked on the terraform-ibm-modules/stack-ibm-core-security-services repository to update the Reference Architecture Documentation, ensuring alignment with the latest IBM Cloud service changes. Focused on enhancing documentation clarity and maintainability, the work involved editing Markdown files to update service names, revise the last-updated timestamp, and provide explicit integration guidance for compliance services. This documentation update aimed to streamline onboarding for new users and reduce the risk of misconfiguration within the security stack. Leveraged skills in technical writing and documentation best practices, using Markdown to deliver clear, accurate, and up-to-date guidance for teams working with IBM Cloud security services.
