PROFESSIONAL EXPERIENCE

NOC Engineer — Columbus (Internet Service Provider), Ternopil, Ukraine | March 2025 — September 2026
• Monitored availability and health of ~4,500 network devices serving 100,000+ subscribers 24/7 using Zabbix

• Administered Linux server operating systems (Debian, Ubuntu): DNS, DHCP, NAT services and SSH access.

• Monitored network activity for anomalies and contributed to network protection measures: firewall rules,
Suricata (IDS), Fail2ban and network auditing with Nmap.
• Maintained technical documentation and handed over incident status between shifts.
