    “This is the programmer you have always dreamed about. His programming skill is excellent and he completes the project ontime and on-budget. Sergey's English skills are really good (for a non-native speaker) and he will stay online during the night so you can chat during your daytime. You will not be sorry if you choose him. I promise!”

    “I have been programming professionally and managing projects for over 10 years and Sergey is one of the best programmers I have ever worked with. He delivers on-time, on-schedule and his technical knowledge is extensive. Sergey is available via cell phone or instant messenger and I would rate his understanding of written and verbal English at an 8 out of 10. He is not a native speaker of English but I have never found that to be a barrier to communication. If he bids on your project, you would be doing yourself a huge favor picking him.”
