Tri Dang 

Need a professional, productive, and innovative programmer with a reasonable cost? Hire me. I have been programming and getting pays for developing real projects since 2003. I specialize in web development (especially PHP/MySQL), electronic commerce, computer security, and database management system. Just let me know about your interesting projects and ideas, I will make them real. Some of my clients, after working with me via freelance sites, do not use these sites anymore, they work with me directly! I do not only build software, but also build trust.
