What I'm looking for

I'm seeking Network Security, Firewall, Cloud Security, and Networking roles where I can manage enterprise firewalls, VPNs, Layer 7 security, HA deployments, and complex incident resolution.

At HCL Tech, I deploy and manage 100+ Palo Alto and Checkpoint firewalls across enterprise and data-centre environments, configure IPSec and GlobalProtect VPNs, and maintain 99.9% SLA compliance while handling 20+ P1/P2 incidents each month.

I've built my network operations background at Reliance Jio and Ericsson, troubleshooting IP core, access-network, routing, switching, WAN, firewall, and connectivity issues. I work across HA clusters, Panorama, SMS, Layer 7 security controls, packet analysis, change management, and root-cause analysis.
