    It's a wonderful experience. I've worked with a developer who is above all patient and professional, who takes into account all the little details and makes sure that everything is right before moving on to the next stage. In the end, despite a few technical problems with my hosting, he was able to resolve everything, so I can only recommend him.

    Great to work with, I plan to work with him on my own custom CRM system and i will keep modding it forever. He did great work and even stayed awake extra to help me through an issue i had. We are just on our first job and he has been excellent. Cant wait for next round of customizations.
