    “I've outsourced several projects on GAF, and kept some developers and moved on from others. Some developers are challenging to deal with, demand funds up front or simply can't do work they claim. I gave Leon a chance with no feedback for a simple project, based on price rather than crediability which I've never purchase on. To say the least, Leon did EXCELLENT work, in a very quick fashion and exceeded my expectations. His communications is supberb, which I expect. I recommend Leon to anyone and suggest you give this new GAF member a shot.”
