Worked on improving the reliability of the CNI Installer in the kumahq/kuma repository by addressing deployment failures related to chained CNI plugins without a specified confName. Implemented a solution in Go that selects the appropriate validation path based on file extension, ensuring that .conflist files are properly validated and preventing the use of a non-existent default CNI configuration name. This backend development effort stabilized cluster onboarding and reduced support overhead by eliminating validation errors during installation. Demonstrated skills in Kubernetes CNI, system administration, and code review, with a focus on robust validation logic and cross-environment deployment reliability.
