What's the difference

Since 2008, I have developed a wide range of scripts, from parser
tool to complex social network. I use HTML, CSS and Javascript (jQuery) for client-side programming and various of technologies (Ruby on Rails, PHP, MySQL, SQLite) for server-side. I can't stand still, I need always to improve my skills, learn new technologies, keep abreast of latest IT solutions. I know and have experience in many technologies, solutions such as AJAX, Git, Heroku, Amazon AWS, Stripe, MVC-frameworks, Linux.

“Just some background, I'm a longtime buyer on oDesk. I'm very familiar with the process, so my reviews mean a lot more than your avg odesk buyer.To me, most of the developers on oDesk, promise the world, and deliver poor goods. Because PHP among other languages are pretty much a commodity right now, it's hard to sift through the shit (try finding a quality graphic designer on oDesk, it's impossible). One of the main problems on oDesk is that developers want to get things done as soon as possible without doing it right the first time because most buyers don't give a proper Scope, QA, and/or know what they're doing. This results in a lot of back and forth and wasted time. Sergey took the time to figure out the scope and understand the reason for what I was doing so he could write better code. What that means is not a lot of back and forth, constant communication, and I think in the first time in oDesk history, something done right the first time. I will use Sergey over and over again and hope he will do as good of a job for me next time as he did this time.”
