PROFILE

Zuzana Lietavcova

Worked on the castai/k8s-agent and castai/helm-charts repositories to deliver new Kubernetes features and improve operational workflows. Over three months, built CronJob resource support and expanded monitoring capabilities by extending the informer factory and updating tests, using Go and Kubernetes APIs. Introduced native Vertical Pod Autoscaler collection with unstructured resource handling, and enhanced RBAC permissions in Helm charts to strengthen governance. Enhanced the Recommendation specification with new fields for resource limits and container runtime configurations, adding deep copy functions for data integrity. These changes improved workload configurability, operational visibility, and deployment reliability across Kubernetes environments, demonstrating strong backend and DevOps skills.

January 2026 monthly summary focusing on business value and technical achievements. Focused on improving autoscaling observability and resource governance by delivering Vertical Pod Autoscaler (VPA) support in the Kubernetes agent and expanding RBAC for VPA in Helm charts. Key work included enabling native VPA collection in the k8s-agent with a refactor to unstructured handling to support dynamic Kubernetes resources, and adding new RBAC permissions for the VPA in the CAST AI agent via helm-charts. Impact includes improved visibility into VPA autoscaling behavior, enabling proactive tuning and potential cost optimization, along with strengthened governance through precise permissions. Technologies demonstrated include Kubernetes API, Vertical Pod Autoscaler, unstructured types, RBAC, and Helm charts.
