## About

I’m a Network Engineer specializing in high‑availability enterprise networks, with hands‑on experience across NOC operations, cloud networking, data center infrastructure, and network security\. I focus on building reliable, secure, and scalable networks that support global business operations\. Over the years, I’ve worked in large\-scale enterprise environments, supporting complex infrastructures across routers, switches, firewalls, VPNs, MPLS, SD‑WAN, and cloud environments\. My strengths include troubleshooting high‑severity issues, optimizing performance, reducing MTTR, and delivering seamless connectivity across distributed systems\. I enjoy working at the intersection of network engineering \+ cloud \+ automation \+ security, and I actively invest in learning modern technologies like VXLAN/EVPN, MP‑BGP, Palo Alto Firewalls, and Python/Ansible automation\. What I Bring: Expertise in Routing & Switching \(BGP, OSPF, VLANs, STP, EtherChannel\) Experience in Data Center networking — VXLAN, EVPN, MP‑BGP, Spine‑Leaf Strong in NOC operations, P1/P2 handling, RCA writing, and incident response Skilled with MPLS, SD‑WAN, IPSec/DMVPN/GRE VPNs Cloud networking fundamentals for AWS/Azure/GCP hybrid networks Firewall & security exposure — Palo Alto, zero‑trust concepts, encrypted tunnels Monitoring tools — PRTG, Grafana, Kentik, ThousandEyes, Zabbix, SolarWinds Automation — Python scripting, Ansible playbooks Documentation, ITIL framework, process improvement, and cross‑team collaboration My Work Philosophy: Keep networks secure\. Keep them fast\. Keep them available 24/7\. And whenever possible—automate the boring parts\. Looking Ahead: I’m currently growing in areas like cloud networking, SDN, network automation, SRE practices, and advanced security, and I’m working toward certifications like CCNP / PCNSA to deepen my expertise\. If you’re building modern, cloud‑driven, secure network infrastructure—I’d love to connect\.
