Hello everybody. I am from China and I got the technical education at Tshinghua University. After graduation, I have been working at a big IT company in Beijing. Now I am looking for job on this site and I think that it gives me a good another opportunity for me to advance my life. As usual freelancers say that "I can do anything and do it perfectly". But I don't say so, because I hate to tell a lie to my clients and I like to say only a truth to them. If you want to work with me, I will do my best for your request even if it is too difficult with my capability and at last I will give you the satisfactory result. I always want to satisfy my clients. Doing so, I am studying new fields of IT top technologies and I am working hard all day and night. So I want to say you - my clients, "I WILL DO MY BEST". I will never disappoint you. Thanks for your kind attention for my long introduction. Best regards.
