PROFILE

David Han

David Han developed and enhanced cloud infrastructure tooling across multiple DataDog repositories over a two-month period. He built a Cloud Cost Management integration for AWS CUR 2.0 within the DataDog/cloudformation-template repository, introducing a new CloudFormation template and updating the Datadog API with a dedicated configuration endpoint and improved versioning. In DataDog/datadog-serverless-functions, David automated the forwarder release process by generating and uploading production version metadata using Python and JSON scripting. He also improved the DataDog/terraform-provider-datadog by removing unnecessary warnings for stable AWS account operations, streamlining API configuration and clarity. His work demonstrated depth in Go, Python, and DevOps practices.

January 2026 monthly summary focusing on key accomplishments across two repositories. Highlights include delivering a Cloud Cost Management integration via a CloudFormation template for CUR 2.0 with Datadog, and enhancing the Datadog Forwarder release process with automated version metadata generation. Key achievements and deliverables: - DataDog/cloudformation-template: Implemented Cloud Cost Management (CUR 2.0) integration using a new CloudFormation template and added a CCM config endpoint in the Datadog API. Included functional changes such as a dedicated endpoint rename and a POST method change, plus a version bump to reflect the updated API surface. Commits: 53abe6e05e707b9cc623ca15ca5e99c2544318a0; ab6408e17d8680288b1e28bb1109ab3d4e83788f. - DataDog/datadog-serverless-functions: Enhanced the forwarder release workflow by adding generation and upload of a versions.json containing production release version information, sourced from GitHub. Commit: 386073681ac6a32e09297012c6683eef098d82b6. Impact and outcomes: - Improved cost visibility and governance with CUR 2.0 integration, enabling better cost-aware decision making for cloud usage. - Faster and more auditable releases through automated version reporting, improving traceability across production deployments. - Stronger alignment with source data and release governance by deriving version information directly from GitHub. Technologies and skills demonstrated: - CloudFormation templates, AWS Cost and Usage Reports (CUR 2.0), Datadog CCM integration, Datadog API design - API changes (endpoint renames, HTTP method changes, versioning) - Release automation scripting, version metadata generation (versions.json), GitHub data retrieval, JSON generation - Cross-repo coordination and end-to-end delivery for production releases
