What I'm looking for

I want to build secure, high-availability enterprise networks where I can own firewall/VPN operations, troubleshoot complex LAN/WAN issues, support migrations, and collaborate with teams and vendors to meet security and uptime standards.

I’m a results-driven Network Security Engineer with a strong focus on securing and optimizing enterprise networks. I bring hands-on expertise in firewall management, network design, implementation, and migration projects across multiple platforms.

In my current role, I manage and support enterprise network and security infrastructure, including Cisco switches, Cisco ASA/Firepower, FortiGate, Palo Alto Firewalls, Meraki, Ruijie Networks, and Cambium Networks. I handle Layer 2/Layer 3 switching, firewall configuration, VPN management, and security policy administration to keep operations secure, reliable, and compliant.

I’ve also delivered stability and uptime through structured troubleshooting of complex LAN/WAN issues and proactive support. At Airtel and earlier, I led incident and service request handling, coordinated vendor support, and improved fault management, performance monitoring, and 24/7 centralized support workflows.

Across roles, I’ve strengthened network access and security using controls like 2FA, VPN user account management, IP whitelisting/blacklisting, NAT rule administration, and zone-based firewall policies. I enjoy collaborating with cross-functional teams and vendors to plan, design, deploy, and support scalable infrastructure—from upgrades to new deployments.
