Network setup Scammer. He didn't do any work, charged for 5,000 USD for work during a time that we were not in communication, I was not on upwork activity, he had no work assigned to me. Upwork did nothing to help me get my money back once I realized what was going on. Save your time and money - go else where.

Googled for answers and figured out but used twice as much time as promised.
I also had questions that he could not answer.
