Senior Systems Administrator at Lympha Technologies, managing VMware infrastructure for Emilia-Romagna Regional Government and maintaining continuity across hundreds of servers.

Italy

Message

At Lympha Technologies, where I consult for Emilia-Romagna Regional Government, I independently managed VMware infrastructure supporting hundreds of servers. I planned and executed upgrades and VM migrations while minimizing service disruption.

I configured and monitored vSphere Replication and verified recovery plans to support Business Continuity and Disaster Recovery. I also used VMware Aria Operations to monitor performance and capacity, and installed VMware Skyline Health Diagnostics for proactive issue detection.

Across public-sector and transportation environments, I’ve administered Windows Server, Active Directory, enterprise storage, and server firmware lifecycles. Since 2018, I’ve worked fully remotely, managing priorities, changes, and deadlines autonomously.
