Worked on the oracle/terraform-provider-oci repository to deliver Zerotrust Packet Routing (ZPR) security enhancements for the HeatWave service, focusing on strengthening the security posture of MySQL DB systems and replicas. Leveraged Go and HCL to update Terraform configurations, ensuring new security attributes were properly integrated and propagated. Developed and expanded integration tests to validate ZPR behavior and end-to-end security attribute handling across OCI deployments. Updated documentation to provide clear guidance on the new Zerotrust features and their usage. The work emphasized cloud infrastructure security, reliability, and comprehensive validation, reflecting a methodical approach to enhancing OCI deployment practices.
