Senior IT Infrastructure Support Technician at Nielsen, handling global Sev-1 incidents and leading shift operations.

At Nielsen, I lead daily shift operations and mentor L1/L2 engineers while monitoring global infrastructure. I serve as an escalation point for Severity-1 outages, using LogicMonitor to support troubleshooting and minimize business downtime.

I oversee change requests and write Standard Operating Procedures to support consistent operations. Earlier, at Sapiens and other employers, I worked across cloud and infrastructure support, system administration, and end-user IT assistance.
