Joe is one of the best programmers I have ever worked with. He is extremely intelligent, creative at solving any problems, very hard-working and an excellent communicator. He was able to implement any feature I wanted, even if he had to read and learn about new APIs or create custom code. A+++ the best of the best.

Joe was my first experience using freelancer.com to find developers for one of my projects. He was an absolute joy to work with and was able to give constructive feedback and help me design a project that would meet my needs. He is a quality developer who understands the development cycle and what is needed to create a robust tool. I will definitely hire again.
