At Optiv, I manage network security operations across three enterprise client portfolios, maintaining a 99.99% network uptime baseline with Zscaler and Palo Alto Networks solutions.

I've led Zscaler Client Connector upgrades for 2,000+ users and tunnel migrations for 800+ users, while improving security posture through ZIA, ZPA, ZDX, CASB policies, and platform access reviews. I also onboarded 35+ sites to Imperva and Cloudflare WAF environments, reducing critical application-layer threats by 95% through SSL certificate updates, WAF rules, and policy improvements.

Previously at Accenture, I supported branch network stability across 120+ sites on a Verizon project spanning 8,000+ sites, working with Fortinet firewalls, Versa SD-WAN, Palo Alto firewalls, and Cisco routing and switching.

My foundation at Hewlett Packard Enterprise included Tier 1 and Tier 2 support for Aruba and Cradlepoint environments across 10,000+ sites, while maintaining 100% SLA compliance across 1,500+ service requests, incidents, and changes. I bring 8+ years of hands-on network security experience, a strong client focus, and a practical approach to resolving production issues.
