The second time to hire FeiXiang for two small development tasks. He always can pick up the problem statements very fast and evaluate the problem and also left out parts in order to make everything clear. Patient guy to work with which make me decide to cooperate with him on an upcoming project which is worth nearly 6 digits. This is the trust I gained from him and will definitely recommend you to hire him one day. Hope our cooperation has a good result and come back and give him a review.
