Developed integrated IDP and PO endpoints within the harness/harness-go-sdk repository to enable CRUD operations on entities and versions, incorporating Git-driven management for seamless version control and traceability. Enhanced the harness/terraform-provider-harness by adding resources for IDP catalog entities, environments, and blueprints, while introducing Git integration to support importing catalog entities directly from repositories. Leveraged Go, Terraform, and RESTful API development to streamline provisioning and automation of IDP resources, improving reproducibility and workflow alignment for product teams. Focused on infrastructure as code and backend development, the work established robust foundations for Git-backed catalog management and automated environment provisioning.
