About Me

I own incidents end to end: triage, root cause, vendor coordination and the documentation that stops the next engineer repeating my troubleshooting. My work covers Tier 1 ISP and fintech networks, from PAN-India GPON access to the firewall and VPN estate across six data centres.

About

Availability, security and performance, in that order of urgency

I'm a results-driven network engineer with 4.9+ years across Tier 1 ISP and fintech environments, currently leading infrastructure operations at Mosambee, a PineLabs company. My work sits between availability, security and performance: keeping mission-critical systems up while hardening the perimeter around them.

I've operated multi-vendor stacks across Cisco, Juniper, Nokia, FortiGate and Palo Alto, from PAN-India GPON access networks at Reliance Jio, to carrier-grade Ethernet circuits at Zayo, to the six-data-centre firewall and VPN estate I run today. I'm comfortable owning an incident end to end: triage, RCA, vendor coordination and the documentation that keeps the next engineer from repeating my troubleshooting.

Outside production tickets I build small internal tools, such as NOC dashboards, alerting scripts and automation around the platforms I manage, to cut down repetitive manual work.
