At Ericsson, I manage deployment and operations for the Ericsson Wallet Platform, maintaining 99.9% uptime across a multi-site infrastructure. I also administer F5 LTM, GTM, and ASM platforms integrated with LAN/WAN networks.

I support hybrid cloud connectivity by configuring and monitoring workloads on Microsoft Azure with Azure Monitor, VNets, and ExpressRoute. I’ve also participated in platform migration initiatives to help transition critical systems while minimizing operational disruption.

Earlier, at DXC Technology, I supported more than 110 global clients in a shared network environment and managed AWS VPC and EC2 instances. My background also includes network security, Cisco routing and switching, and LAN/WAN support.
