    “The project had a lot of technical difficulties but that was the nature of this project as we were modifying existing scripts. Yilong did a lot of hours extra due to these problems and is a hard worker who is honest. We didn't hit the time-frame but that was due to unforeseen problems mid-project. Would recommend!”
