PROFILE

David Han

Over a two-month period, this developer delivered three features across Datadog repositories, focusing on cloud cost management and API stability. In DataDog/cloudformation-template, they implemented AWS Cloud Cost Management integration using CloudFormation and enhanced the Datadog API with a new configuration endpoint, including endpoint renaming and HTTP method updates. For DataDog/datadog-serverless-functions, they automated release version tracking by generating and uploading a versions.json file sourced from GitHub, improving release traceability. Additionally, in DataDog/terraform-provider-datadog, they streamlined developer experience by removing unnecessary warnings for stable AWS account operations. Their work leveraged Go, Python, CloudFormation, and API development expertise.

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
