Madhu S. enhanced credential management and deployment flexibility by implementing plain-text AWS KMS ARN support across the harness/harness-go-sdk and harness/terraform-provider-harness repositories. Using Go, HCL, and YAML, Madhu introduced new configuration fields and updated API surfaces to allow KMS ARNs to be provided as plaintext or secret references, addressing diverse credential storage needs. The work included expanding test coverage to validate both plaintext and secret-referenced ARNs, as well as updating documentation to streamline developer onboarding. This focused, cross-repository effort demonstrated depth in API design, backend development, and configuration management, resulting in more robust and flexible cloud connector integrations.
