Worked on the openshift/assisted-service repository to deliver explicit control over cluster installation by introducing a control_plane_count field in the InstallCmdRequest API. This update replaced the previous high_availability_mode setting, enabling more predictable and accurate configuration of control plane nodes during automated deployments. The approach focused on enhancing API clarity and reducing the risk of misconfiguration, directly addressing deployment correctness. Leveraging Go for backend development and YAML for infrastructure as code, the work improved the reliability of cluster provisioning workflows. The contribution centered on API design and backend implementation, reflecting a targeted, impactful change within a complex deployment system.
