Solid understanding of container orchestration platforms, including Kubernetes-based distributions, covering cluster architecture, networking, air-gapped operation, container image handling, and YAML manifest structures (e.g. Docker, k8s, k3s, containerd).

Working familiarity with Zabbix components including servers, frontends, templates, REST APIs, and common protocols (e.g. SNMP, LLD, Redfish, SSH, HTTP/HTTPS, WinRM), as well as integration of external systems (e.g. Trellix ePO, Veeam BRS) and troubleshooting of data pipelines.
