I am a Network and Security Engineer with over four years of experience in enterprise networking, routing and switching, firewall administration, VPN technologies, and network infrastructure operations. My technical experience includes Cisco, Palo Alto, Fortinet, Check Point, BGP, OSPF, and network monitoring platforms such as Zabbix and Cacti. I have supported backbone network operations, designed and maintained enterprise network environments, troubleshot complex connectivity issues, and implemented security and high-availability solutions. I also have experience with virtualization, server administration, technical documentation, and hands-on network engineering training. My goal is to build reliable, secure, and scalable network infrastructures while continuously developing my expertise in network security and automation.
