Function and design update

“Sergei helped me with some updates on a proof-of-concept project.Even though the base was made by another programmer he had no problems understanding the structure of it and build on it.Met all deadlines and was i general easy to work with.My only issue was communication, which was a little difficult the first week. I won't blame it on Sergei because it was my first time with oDesk and I come from Scandinavia so we have an slightly different way of working. Once I realized that I had no problems.Recomend working with Sergei and would hire him again for sure.”
