    “David was professional, flexible, skilled, and dedicated. He replied to my urgent issue immediately, and hung around while I tried to gather the details that he needed, since I was trying to pick up the pieces from where my previous developer left off. He was very patient and understanding in helping me figure out what he would need to get the job done. We are in different time zones, and David kindly stayed up late into the night to complete my urgent project. David completed the project very quickly and did a great job at dissecting and fixing the problem. I plan to hire him again in the future.”
