What I'm looking for

I’m looking to drive robust, secure network operations for critical environments—firewalls, VPNs, and routing—paired with strong monitoring and troubleshooting. I want to continue 24/7 reliability work and grow automation and VMware/AWS network capabilities.

I’m a dedicated Network Engineer with 15+ years of experience installing, configuring, and supporting complex network systems end-to-end—from firewall and VPN deployment to day-to-day monitoring and troubleshooting. I’ve built and maintained secure, highly available connectivity for multiple university campuses and data centers, ensuring 24/7/365 network availability.

I specialize in Cisco, Juniper, and Palo Alto/FortiGate security and routing, including ASA remote access VPNs, site-to-site VPN tunnels, and core routing protocols such as EIGRP, RIP, OSPF, and BGP. I leverage CiscoWorks and Nagios for monitoring, diagnose issues with firewall logs plus Splunk, Wireshark, and NetFlow Analyzer, and improve performance with tools like F5 load balancing, Infoblox DNS, and Cacti graphing—while also applying network automation using Python and supporting VMware and AWS network infrastructure.
