    Software Engineer over here! Domain-driven design enthusiast with passion for structuring flexible OO design with PHP.

I'm developing enterprise web applications, file sharing systems, websites, web application frameworks, etc. Achieving high quality of code, good performance and reusable object-oriented software design is my primary goal when working. I don't underestimate documentation as my source code is always well documented, with end-user manuals when needed. In the last two years I've gained rich experience with Dependency Injection and Service Locators and successfully applied those approaches my projects. I'm always ready to learn new approaches, if they could make my work quicker and easier. I have experience in educating developers. I've been teaching students PHP, Zend Framework(basic and advanced levels), MySQL, jQuery, Design Patterns and etc. I'm seeking to develop big and complex web applications using the last technologies and software development methodologies.

    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.
