Worked on DNS system enhancements for the k8gb-io/k8gb repository, focusing on improving DNS resolution reliability within Kubernetes environments. Developed recursive CNAME handling in the util.Dig utility and extended CoreDNS service logic to accurately return ClusterIP or LoadBalancer IPs based on the service type. Leveraged Go for backend development, integrating feature-flag controlled rollouts to enable gradual adoption of the new ClusterIP behavior. The work addressed the need for precise IP targeting in Kubernetes DNS infrastructure, ensuring that both ClusterIP and LoadBalancer services are resolved correctly. Demonstrated expertise in Go, Kubernetes networking, and DNS resolution without addressing major bug fixes.
