Robert Dusing | IT support and network technician

About

I spent four years on an enterprise help desk at Atos, triaging and escalating network, hardware, and software incidents through ServiceNow. Outside of work I build and troubleshoot my own network: DNS filtering, VPN tunneling, subnet routing, and LAN administration.

I also have a bench-tech background. At Batteries Plus I do board-level phone and tablet repair, microsoldering, automotive key programming, and battery diagnostics, and I train the technicians who work with me. I like finding the real cause of a problem, not just the symptom.
