Gabriel Wergba

I’m a Senior System Administrator who has maintained IT infrastructure uptime for multi-site operations supporting over 150 users, improving system availability to 99.8%. I administer Windows Server and Linux environments, and I virtualize with VMware and Hyper-V to keep services stable and scalable.

I build resilience into day-to-day operations—leading backup/disaster-recovery improvements that cut restore time from 6 hours to under 2 hours. I also automate routine work with PowerShell scripts (like AD provisioning and patch scheduling), reducing manual workload by 35%, while coordinating endpoint deployments for stronger compliance reporting.

Security and service quality are central to how I work: I collaborate with Security and Compliance teams to enforce ISO 27001 controls, reducing recurring incidents by 40%. Earlier, I ran network administration (AD, DNS, DHCP) and provided hands-on support as a Computer Lab Technologist, which keeps my troubleshooting and customer communication focused on fast, documented resolution.
