In February 2026, Reina contributed to the DataDog/dd-trace-js repository by establishing explicit code ownership for AWS Lambda components. She updated the CODEOWNERS file to assign the APM-Serverless team, clarifying responsibility for serverless monitoring code and streamlining pull request reviews. Reina’s work focused on code ownership management and cross-team collaboration, leveraging her understanding of Git workflows and AWS Lambda environments. By improving accountability and maintainability, her changes reduced risk for Lambda-related updates and enhanced code quality. Although the scope was limited to a single feature and did not involve bug fixes, the update addressed a key governance need for the project.
