    iOS Game reskin - hobbit Jetpack
    Jin Chenggong is the best developer on odesk by far!!!! Great skills, great communication skills, very experienced programmer. Jin was very helpful and he understood my requirements immediately. For my project that implements Game task reskin, he is skilled and experienced. Communicating with Jin was a pleasure. He was straightforward and wasted no time in pointing out the limitations and future problems of the app idea. Everything was clear and confusing points were written and explained in black and white. By communicating with him, I have ended up with an even better end product than my original idea. His speaks and writes perfect English. He understands all the common terms used in the market and programming. He summarizes the understood points and agreements at the end of every meeting and knows what he has to do after every meeting. The results in the next meeting always reflect his perfect understand of our exchanges before. If you are looking for a smart and flexible programmer, Jin is the one. Skills, experience and communication skills are the standout qualities of Jin from my experience with him. He knows his skills, the market and he wants to know you and your users as well. I definitely recommend him to anyone looking to develop an app. He is the perfect partner. And was willing to share his knowledge with me (even though I'm renowned for asking too many questions) Jin was able to understand my design ideas and came back from his graphics designer with graphics that after a few meetings we had to perfection. I have learned a lot from this whole process and without Jin I probably wouldn't have had this app developed. Jin's work ethic is unlike anyone else I've met, he worked unreal hours to 4&5am and was always there when I needed to ask another question. Jin if your reading this, thanks very much again. I hope you will work with me again!!!
