Network & security engineer building resilient routing, firewall, and cloud connectivity.
United StatesWhat I'm looking for
I’m a Network & Security Engineer with 4+ years of experience designing, implementing, and troubleshooting enterprise network infrastructure end to end. I focus on routing and switching across multi-site environments, while enforcing strong security controls through firewall policy management, ACLs, and VPN configurations.
In my current role, I design and manage Cisco-based enterprise routing and switching, configure BGP and OSPF, and implement VLAN segmentation to improve performance and availability. I administer IPSec and SSL/TLS VPNs, support WPA2 Enterprise wireless deployments with WLCs, and optimize SD-WAN configurations to strengthen WAN resiliency and cost efficiency across branches and remote offices.
I also build hybrid cloud connectivity using AWS and Azure networking services, monitor health and performance with Splunk and network monitoring tools, and resolve escalated incidents using Wireshark and NetFlow analysis. I document network standards and configurations and automate repetitive provisioning with Python—cutting device configuration time by ~40% in my home lab work—so teams can deliver faster, safer, and more reliably.
