Oksana Grishchenko contributed to the percona/percona-helm-charts repository by engineering robust Kubernetes operator features and infrastructure enhancements. She developed and aligned CustomResourceDefinitions (CRDs) and Helm charts, introducing validation webhooks and RBAC improvements to streamline deployment and governance. Her work included implementing end-to-end LoadBalancerConfig lifecycle management, integrating DatabaseCluster references, and automating service management through updated cluster roles. Using YAML, Helm, and Kubernetes, Oksana focused on reducing configuration errors, improving deployment reliability, and supporting secure, automated operations. Her contributions demonstrated depth in DevOps practices and cloud infrastructure, delivering maintainable solutions that enhanced both stability and operational feedback in production environments.

September 2025: Implemented a key RBAC enhancement for the Everest Operator within the percona/helm-charts repository to enable management of Kubernetes services. Updated the cluster role to grant service-related permissions, establishing automated service lifecycle management, improved security posture, and a foundation for future operator capabilities.

Month: 2025-07. Delivered a new Monitoring Configuration Validation Webhook for percona/percona-helm-charts, intercepting CREATE and UPDATE requests for monitoringconfigs to enforce predefined validation rules. This work reduces configuration errors, improves cluster reliability, and aligns with governance and security goals. It also establishes a pattern for future validation hooks and strengthens operational feedback during deployments.
