atif Muhammad

I am a certified network and security engineer (CCNP Enterprise, PCNSA, NSE 4) with over three years of hands-on experience designing, implementing, and securing enterprise-scale network infrastructures.

I have delivered high-availability, multi-site solutions and led migrations with measurable results — including a multi-site network maintaining 99.9% uptime, a legacy firewall migration completed early and under budget, and a Palo Alto NGFW rollout that reduced security incidents by 25%.

My technical practice spans Cisco IOS/NX-OS, ASR/ISR routers, Catalyst/Nexus switches, Palo Alto and Fortinet firewalls, WAN routing (OSPF, EIGRP, BGP), VPNs, and automation using Python. I regularly use tools such as SolarWinds, Wireshark, NetFlow, EVE-NG and GNS3 to baseline performance and troubleshoot production issues.

I collaborate across teams to deliver resilient, secure, future-ready networks, and I’m motivated by reducing downtime, improving performance, and automating repeatable processes to free teams for higher-value work.
