    “Gautum is an expert coder. He really knew what he was doing and offered creative solutions to problems and suggested creative new implementations and ideas that I did not think of. A lot of programmers just do the job they are told to do. But Gautum thinks things through clearly and offers ideas to make the project even better. He is a very talented programmer and I have already hired him for my next project. I have a service that has a lot of users, so I want to find the best because my reputation is on the line. I am glad to have chosen him for my project.”
