What I'm looking for

I want to keep securing enterprise networks at scale—owning firewall policy, Cisco switching/WLAN support, and monitoring—while delivering fast troubleshooting and reliable upgrades for customers, even under time crunch schedules.

I’m a Network Security Engineer with 2.5+ years of experience managing large-scale enterprise infrastructure across 50+ sites globally. I’m hands-on with Cisco Switches, FortiGate firewalls, Cisco WLC, and network monitoring tools—so I can handle complex situations under tight schedules.

In my current role as a Technical Lead at HCL Technologies Limited (Sensata Technologies project), I work as a FortiGate Specialist supporting FortiGate 101F, 61E, 601E, 1101E, and Cisco ASA 5500/WLC 5500/vWLC 9800 environments. I configure inbound and outbound firewall policies, VLANs, trunking, inter-VLAN routing, STP, EtherChannel, and AAA with TACACS+—including port security for stability and redundancy.

I administer 50+ FortiGate devices, managing inbound/outbound security policies for web filtering and application control, and handling NAT/PAT and routing policies via SD-WAN and FortiGate firmware upgrades. I also manage 15+ Cisco ASA firewalls, coordinate AP deployments across 4 Cisco vWLC/WLC setups, and troubleshoot hub-to-site/site-to-site connectivity, wireless issues, and ISE authentication problems.

I rely on SolarWinds NCM/NPM for monitoring, configuration backups, and log review, including monitoring Fortinet utilization, sessions, and bandwidth usage. I combine network security with automation thinking through Python scripting (including a Cowrie honeypot project) and support strong delivery through my Cisco CCNA, Microsoft Azure AZ-900, and Fortinet NSE1–NSE3 certifications.
