Developed and delivered Customer Cost Anomaly Detection for the oracle/terraform-provider-oci repository, enabling proactive cost governance within Oracle Cloud Infrastructure. This work introduced new Terraform resources for cost alert subscriptions, cost anomaly events, and analytics, all integrated through Go-based SDK and Terraform configuration updates. By wiring these features into the provider, the solution allows users to monitor, detect, and respond to cost anomalies automatically, reducing financial risk. The implementation leveraged skills in API integration, cloud infrastructure, and SDK development, resulting in end-to-end support for cost anomaly detection and analytics, and enhancing the provider’s capabilities for automated cost management.
