Denis was incredible. Many other developers failed at this task, and while it took some time, he did not give up until he accomplished exactly what we were looking for. It was certainly a hard task and I'm glad we found him. Highly recommend!

I've worked with Denis on numerous occasions. He's honest, trustworthy, knowledgeable, and FAST! So far, I haven't come across a problem Denis has not been able to solve. Owning a business is not easy, and I've had many sub-contractors come and go over the years. Denis, I'll be keeping around! It's hard to find talent that is trustworthy and values your time enough to get things done, when expected.
