About

Technology strategist with 25 years of experience across the full service provider network, covering service delivery platforms, the core, transport, aggregation and access layers, and the complete lifecycle of architecture, design, deployment and operations.

I provide advisory and solution architecture for specialised network initiatives. My experience spans carrier-grade EMS and NMS, OSS service assurance, IPTV and IMS headends, AAA and BSS billing, IP/MPLS and DWDM transport, aggregation, and triple play broadband access for Tier-1 operators and equipment manufacturers.

My current focus is India’s digital infrastructure, including national fibre, rural and last-mile connectivity, and smart cities, along with the use of AI and cloud-edge technologies in service provider networks. I have held various technology leadership roles across the industry.
