    PHP Web Development

    Bahrain - Tests: 2

    Programming is my life and my language. My brother knew I was a programmer before I did. He bought me that first book when I was about 10. That was 23 years ago. I am a programmer with experience in many languages, platforms, and operating systems. I love working with small companies and startups. Whether you need someone to lead your team, program into the wee hours of the night, or just need someone to talk to, I can help. 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 design, development, and programming. #1 and All PHP, MYSQL, POSTGRE SQL, JavaME, Javascript, C++, Java J2EE, J2SE.
