Karthik Narayanan developed a comprehensive testing suite for the PEAKS scheduler plugin in the grafana/scheduler-plugins repository, focusing on quality assurance within Kubernetes environments. He designed and implemented both unit and integration tests in Go, targeting the plugin’s initialization, scoring, and node score normalization logic. By validating node score normalization against power models and watcher metrics, Karthik ensured the plugin’s correct behavior in production deployments. His work improved test coverage, reduced regression risk, and enabled safer pull request reviews. This depth of testing supports faster release cycles and greater reliability for the scheduler plugin, reflecting strong skills in Go and Kubernetes.
