Work History and Feedback

  • Mar 2013

    IOS Assistant Developer
    Qingxin is a great application programmer. We gave him a rather complicated project on a tight deadline and he worked nearly around the clock to meet our deadline. He's extreamly dedicated to providing a quality product. He possesses a great understanding of how to create applications from scratch and has offered his suggestions for our builds that we never even thought of... this saved us both time and money. It's also very impressive that he is avilable just about anytime you have a question, he's very responsive and communicates very effectively. Perhaps the best part of all is the quality of his work. His code is very neat and nicely structured making very easy to see exactly how it was created. We are so impressed that we already have another project lined up that we are going to hire his services for again.
