Work History & Feedback

finish my wordpress mobile aite

“STOP LOOKING, JUST GO WITH JIN! I am serious, I have done a lot of work with freelancers through various forums, not just oDesk. Take it from someone with experience. Do NOT scroll past his profile, just hire him. His rate is higher but he is worth every penny! Jin has been an excellent contractor to work with. Upon starting work with oDesk he was a recommended contractor. I had used other contractors as well, but time and time again Jin has surpassed me expectations. He has been honest with his work, and his hours. He can always explain anything he is doing. His communications are just as good as any native speakers. I have already opened up more work for Jin and have recommended him to others. His work is easy for me to understand, always bug free. He's very fast to respond to questions, and is always good at clarifying things. If I dont understand something or dispute something. He has an explanation and we work it out. Honesty, integrity, hard work. You just can't find much better. Contact me if you have any other questions.”
