Thomas Horn

I’m a Senior Network Engineer with over 12 years of experience in complex enterprise environments, where I design and optimize high-performance infrastructures using Cisco and Fortinet technologies. I focus on maximizing uptime and security through advanced routing and troubleshooting, especially in multi-site and hybrid-cloud scenarios.

I’ve led large-scale network migrations, multi-site deployments, and integrations that improve reliability and security across evolving environments. In recent roles, I implemented and upgraded Cisco switching and routing platforms, provided expert-level fault analysis for remote installations, and strengthened documentation to keep production operations running smoothly.

My work also spans automation and cloud-enabled infrastructure changes. I’ve executed campus deployments and feature integrations across Cisco Nexus and Meraki SD-WAN, conducted application server migrations using Microsoft Azure and VMware ESXi, and applied solutions like VRF and VTP to improve security and operational efficiency. I’ve also supported proactive monitoring by leveraging Splunk and FortiSIEM, and I use Ansible to automate information gathering and configuration tasks.

Earlier in my career at Extreme Networks and Brocade Communications, I designed network environments for multiple enterprise customers, deployed and repaired routing protocols (including BGP, OSPF, MPLS, and VxLAN), and mentored engineers to improve day-to-day customer outcomes. I also bring a continuous-improvement mindset from mentoring and escalation work—and, more recently, I’ve been working as a model trainer and STEM subject matter expert to evaluate and improve AI outputs using Python and SQL.
