    “I decided to hire him since he is native from the same country that I am. After some problems with the communication and requirements of the project, he finally delivered the program which did what had to be done. It was still missing polishing and design for the UI, but since I knew a little about code and with the right guidance from this freelancer, I was able to use the program flawlessly. Will hire again because I love my country and I like working with hard-working people! I know we will have a great experience next time since we finished this first project in good terms.”
