Infrastructure specialist at Heidelberg Materials - building, operating, and supporting VMware, Windows, Linux, & Azure environments at enterprise scale from Brno, Czechia.
I'm Sanjay Karki, a Server Administrator at Heidelberg Materials Digital Hub in Brno, Czechia. With a career spanning IBM, Kyndryl, and beyond, I've built deep expertise in VMware ESXi, Windows Server, and Linux infrastructure, from bare-metal deployments to full cloud migrations on Microsoft Azure.
Earlier at IBM, I served as an Incident Manager, leading cross-functional teams through critical incidents, championing process improvement, and building the response-readiness culture that keeps enterprise systems recoverable and resilient.
I started out as a Web Developer in Kathmandu, which gives me a full-stack perspective on every infrastructure challenge. I remain genuinely passionate about programming, science, and technology in their broadest spectrum.
Orchestrated a full VMware ESXi upgrade from v7 to v8 across the datacenter and all remote sites. Led migration of on-premises workloads to Microsoft Azure, reducing infrastructure overhead and improving scalability.
