    PHP/MySQL Developer,Javascript,Client and Server Side exp

    Argentina - Last active: 26 days ago - Tests: 7 - Portfolio: 1

    I started programming computers when I was ten years old, and, over the last 14 years, I've realized that I am, well, a programmer. That said, I do have the "people skills" necessary to remain competitive in the world of programming. When needed, I'm a "sit in the corner and program til the wee hours of the morning geek"... otherwise, I'm just a "fun to talk to, easy to get along with normal person". I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming. I face every new piece of code as a fresh new beginning... a chance to do it even better, while, still using "what works" from the past. My objective, here at oDesk, it to provide potential employers with my expertise in the field of website desgin, development, and programming.
