DevOps Engineer / Linux Systems Administrator
Summary
• DevOps Engineer / Linux Systems Administrator with ~2 years of production infrastructure work in an outsourcing environment, operating client platforms from single-server deployments to large estates with hundreds of VMs and multi‑TB production data.
• Platform operations across Linux (primarily Ubuntu), virtualization (Proxmox/Hyper‑V/VMware Cloud Director), Kubernetes, and production migrations/upgrades.
• Kubernetes delivery and operations: Helm-based deployments, RKE2 + Longhorn for a client platform; implemented Longhorn backups to S3‑compatible object storage (Hetzner Object Storage) with restore validation.
• Observability and troubleshooting: Zabbix as primary monitoring; Elastic Stack used for deeper log analysis and investigations.
Skills
Kubernetes / Containers: Kubernetes, RKE2, Helm, Longhorn (storage; S3 backups/restore), Docker/docker-compose
Automation / IaC: Ansible, Terraform, Bash, Python, Git, GitLab CI/CD
Observability: Zabbix (primary), Elastic Stack
Databases: PostgreSQL, MySQL (monitoring/backups), Redis (basic setup and configuration)
