Worked on the keycloak/terraform-provider-keycloak repository to enhance group management within Terraform by implementing diff suppression for multi-valued attributes in the Keycloak group resource. This approach involved sorting attribute values to ensure deterministic diffs, thereby preventing unnecessary updates and reducing redundant API calls during Terraform plan executions. The work included updating Go-based backend logic and comprehensive test coverage to validate the stability and order of diffs across changes. By focusing on API integration, backend development, and testing, the contribution improved release readiness and plan stability, addressing a core issue of plan churn and enhancing the efficiency of infrastructure as code workflows.
