Worked on targeted improvements across the DataDog/datadog-agent and DataDog/helm-charts repositories, focusing on Kubernetes observability and deployment reliability. Enhanced the Kubernetes API Server collector by updating group resource string validation in Go, allowing group names with periods and improving resource identification. Addressed a Helm chart issue by fixing RBAC rendering logic to correctly handle Kubernetes labels and annotations as tags, updating YAML templates and chart versioning to reflect the change. Demonstrated skills in API integration, Helm, and Kubernetes RBAC, delivering CI-ready changes that reinforced end-to-end correctness of resource tagging and access control across multiple deployment environments.
