I have been working as a programmer for a long time.
Most of my experience focus on web application server side development.
I have faith in what I can do, and I believe that I can do great.
I feel comfortable when writing Java. And always tend to make it better, and make it right.
Really looking forward to find a environment where I can give all I have, and, of course, keep getting better.
