David Han

Worked across multiple Datadog repositories to deliver cloud cost management integrations and infrastructure automation features. Developed CloudFormation templates and Terraform resources in Go and Python to enable AWS Cloud Cost Management (CUR 2.0) and UK1 site onboarding, improving cost visibility and regional support. Enhanced the datadog-serverless-functions repository by automating release version metadata generation, increasing deployment traceability. Upgraded AWS Lambda runtimes to Python 3.14 and improved configuration validation reliability by sequencing Lambda execution with CUR export readiness. Focused on API stability in the terraform-provider-datadog repository, streamlining developer experience and reducing configuration warnings. Emphasized testing, CI validation, and production-ready deployment artifacts.

June 2026: Stabilized configuration validation flow for DataDog/cloudformation-template by introducing a CUR export wait condition before invoking the Datadog API. The Lambda now fires only after DDCURReportDefinition completes, ensuring the CUR export exists when CCM config validation runs. Version bumped to v0.0.5 to reflect the update. This change reduces false negatives in validation, prevents premature API calls, and aligns with the existing BucketWaitCondition pattern for consistency.

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
