    “Meet all requirements and expectations on time.”

    “I haven't been contacted by the service provider since June 26 about the development of the project. Three months ago SergeyPlus has been awarded the Swing trading indicator project. Although I believe SergyPlus is an excellent service provider...I am afraid the trading related nature of this project did not match his skills. On June 26 he sent his last message that he was still trying to understand the details of the project. After that message no follow up has been sent. So I guess he just forgot to report that he was not able to complete the project.”

    “Sergey did the program, but at one stage he stucked and could not fix the bug. I paid another programmer in GAF "Srinichal" $60 to get the bug fixed as i am in urgency. Sergey should have responded to my messages at the least. He is capable of doing things but it would be better if he understands the situation of client and respond them promptly.”
