Megan Du enhanced the DataDog/terraform-provider-datadog repository by implementing a cross-cloud feature that adds Terraform provisioning metadata to cloud configuration API requests for AWS, Azure, and GCP. Using Go and Terraform provider development skills, Megan designed an API extension that introduces a meta field indicating Terraform as the setup method, improving traceability and governance of resource provisioning. The work focused on cross-cloud consistency and observability, enabling metadata-driven tracking of infrastructure changes. Megan’s approach demonstrated depth in API design, multi-cloud integration, and version control, delivering a targeted feature that supports better management and auditing of cloud resources provisioned through Terraform.
