Developed and delivered Vault Connector Integration and Validation for Resource Workspace in the harness/terraform-provider-harness repository, focusing on enhancing secret management within Terraform workflows. The work involved adding support for Vault-based secret provisioning by integrating vault connector functionality directly into the resource workspace and updating validation logic to recognize Vault as a supported connector type. Comprehensive Go-based tests were implemented to ensure robust coverage of vault connector features, contributing to improved security and automation. Leveraging skills in Terraform provider development, backend engineering, and automated testing, this effort streamlined secret management, reduced manual configuration steps, and enabled faster iteration for Vault-backed resources.
