    I had a lot of difficulties trying to find the right freelancer for my project. Many who bided did not even understand the requirements specified. However, John was the only one with a clear understanding of the project requirements and also bided on it with a good proposal on how he would handle the project. He was very consistent with his updates on the progress of the project. The best part about working with him is that he understood the requirements throughly and completed the project way before the deadline.He was very professional. I am very happy with the results and look forward to working with him.
