Delivered multi-region enhancements for AWS Network Manager, including DNS support, security group referencing, and refined routing policy rules to enable cross-region deployments. Addressed core network policy reliability by fixing JSON marshaling and improving test accuracy, reducing flaky tests and streamlining verification. Implemented dynamic in-place VPN routing policy label updates, allowing label changes without recreating VPN attachments and minimizing operational downtime. Validated integration points to ensure backward compatibility, demonstrating robust infrastructure as code practices and efficient provider development workflows.
