    “Wang F. is brilliant, he would first clarify requirements, estimate budget and provide appropriate solution before starting to work, he had never raised up trouble issue for me to solve which I believe he is very professional. During the working process, I do not need to worry about anything, just wait for result and always bugs free. Highly recommended!
