Managed entire network including 3 ESXi hosts with approximately 10-15 guest VMs running on each host. Guest VMs were running Windows 2008-2016 or Ubuntu Linux v16. Also had to manage several physical servers/appliances for faxes and phones. This included the Digium Switchvox phone system which were switched out for 3CX at the end of my tenure there. Programmed a lot of custom scripts and services to help automate tedious processes throughout the business. Managed SQL Servers from 2005 all the way to 2017.

I oversee networking, communications, industrial controls, and electrical engineering among other IT roles.I manage multiple VMware ESXi servers using an iSCSI NAS for the datastore. Some of the guest VM's include a Linux web server, Exchange server, multiple domain servers, file servers, 3CX PBX server, and several virtual desktops. At some of our industrial plants, the guest VMs also include A Milestone XProtect server, terminal servers, and Wonderware Archestra servers.I have interconnected 3CX VoIP PBX servers at 3 locations. 2 locations utilize standard POTS lines connected to an FXO gateway, while the main office location uses 100% VoIP for all calls and faxes, but was previously using a T1 PRI connected to a VoIP gateway for interfacing with the 3CX PBX.Our industrial plants use Milestone XProtect for surveillance and use on average 15-20 PTZ IP cameras streaming live video using H.264 encoding.For firewalls, we currently use Sonicwall, and are in the process of transitioning to Sophos UTM appliances as our support and hardware expire on the Sonicwall devices.
