What I'm looking for

I’m looking for a role where I can ensure stable network operations, support enterprise security compliance, and keep developing in enterprise networking and IT security—through hands-on infrastructure work, monitoring, troubleshooting, and continuous learning.

I’m a Network Engineer with hands-on experience in enterprise LAN and WAN environments, infrastructure operations, and IT security support. I administer routing and switching, manage VLAN/STP/trunking, and handle network troubleshooting for business-critical stability.

In parallel, I support security operations by administering Check Point firewall policies and security rules, and I monitor availability using Zabbix. I also bring a support background from first-line IT help desk work and Security Analyst Intern experience, including phishing and malware analysis and incident reporting.
