United StatesWhat I'm looking for
With over 20 years of experience as a Senior Network Engineer, I have honed my skills in designing, securing, and optimizing enterprise network infrastructures. My expertise lies in Fortinet-based architectures, complemented by proficiency in Cisco, Extreme, Arista, and Juniper technologies. I am adept at network automation and possess a strong background in packet-level analysis and log debugging, which enables me to implement scalable network solutions across hybrid environments.
At EZCORP, I led the enterprise-wide SD-WAN deployment across 1500 retail sites, ensuring secure VPN tunnels for cloud and branch connectivity. My role involved authoring PowerShell automation scripts to streamline router upgrades and conducting deep-dive packet analysis to resolve WAN stability issues. I take pride in mentoring junior engineers and creating comprehensive onboarding documentation, which has significantly improved ramp-up times for new hires. My commitment to maintaining secure configuration standards aligns with PCI-DSS and internal audit requirements, ensuring compliance and operational excellence.
