Observability stacks (Prometheus/Grafana, ELK, Zabbix), incident response, capacity planning, and SLO/SLA design in high-availability environments.

Linux & Systems

25+ years of Linux administration, Bash scripting, networking, and systems-level troubleshooting on everything from VMs to Kubernetes nodes.

Container & Orchestration Platforms

Valeriy works daily with Docker, Kubernetes, Nomad, and Proxmox — covering the full spectrum from local development containers to multi-cluster production deployments.

Docker

Build optimisation, multi-stage images, registries, and Compose patterns.

Kubernetes

Workload management, networking, RBAC, and cluster operations.

Data & Observability

Production experience with MySQL, PostgreSQL, Greenplum, and Oracle databases, combined with observability pipelines built on Prometheus, Grafana, ELK, and Zabbix.
