I build secure, automated enterprise networks across datacenters, campuses, and multi-cloud environments.
United StatesWhat I'm looking for
At Havas, I support an enterprise datacenter migration while deploying Aruba CX, Juniper Mist, Meraki, and Palo Alto network infrastructure across production and distributed office environments.
Previously at Harry Winston, I architected a high-availability Cisco campus network, led the move to Cisco Catalyst Center, and delivered Zero Trust, Wi-Fi 6, SASE-aligned SD-WAN, and automated operations that reduced manual effort by about 30%.
I've also built secure connectivity and access controls for healthcare and multi-site environments using Cisco ISE, IPsec VPNs, Firepower, Azure MFA, monitoring platforms, and Python/Ansible automation. I bring 8+ years of hands-on network engineering experience across media, financial services, healthcare, and corporate networks.
