Worked on the vmware-tanzu/nsx-operator repository to enhance subnet provisioning reliability by addressing a bug affecting L2 subnet gateway prefix resolution. Applied Go and backend development skills to modify the GetGatewayPrefixOfSubnet function, introducing a fallback mechanism that retrieves the gateway prefix from subnet status when the primary method lacks data. Expanded automated test coverage to validate behavior for subnets with and without gateways, ensuring robust handling across scenarios. Validated the fix in a live testbed, confirming that SubnetPortReady statuses now reflect accurate configurations. This targeted change reduced misconfigurations and improved the readiness of gateway and prefix resolution for customer environments.
