I also configure Cisco Secure Firewall 1220CX, routers, and site-to-site IPsec VPN tunnels, and support Cisco wireless controllers and more than 1,200 access points.

Previously, I maintained network infrastructure and FortiGate firewalls at The Oberoi Group, and provisioned AWS resources as a Jr. Cloud Engineer (Intern) at Optimum Research Solution.
