Twitter and Facebook visualization

“We really liked James and his way of working. We went for him over other lower priced contractors because we thought that James' combination of tech. skills and native English would mean that he would be cheaper in the long run. We were proved right when James instinctively grasped the essence of what we were trying to do: which meant less rounds of changes, lower costs and a quicker time to market. What is interesting about James is that he combines good tech skills with a good eye for design. These 2 skills are hard to find in the same person. To sum up, we'll definitely be using him again and have no reservations in recommending him.”
