Testimonials
...I cannot say anything but no one could do it except Sergey this guy is good, and I will work with him again
...Great guy to work with. He is very responsive, he was well within my budget and overall delivered a great product to me. I will definitely use him again.
...Sergey is a good programmer and has proven he possesses a great deal of patience and an ability to solve tricky problems. I will continue to use him.
...Sergey tackled a very difficult problem and did so under the requirement of utilizing unsupported technology (i.e. a deprecated ActiveX control from Adobe). Any budget overages were purely the result of the undefined science experiment he was required to perform. We strongly recommend Sergey for future projects and can provide a positive work reference.
