Additional information Client Testimonial
M.S., Manager, The Deters Company, dba Wendy's
I just wanted to take the time to let the company know how kind, patient, and knowledgeable Andrei was. He took the time to help me understand the firewall and network connections while assisting to resolve my software issues. I wanted to make sure that you noticed he went above and beyond, helping a guy who flips burgers understand the network.
