Project rating:

Excellent, excellent, excellent. Extremely patient, absolutely knows what he is doing, has good suggestions, even researched plugins and other things for me. All around did a wonderful job. Very friendly, and got work done at a good pace. He even did some things for me that I am sure were not part of the project but he did not complain or say no to me once. Super job, super guy A+

Bruno was a great person to work with. I am about to launch my business Ancona Wellness www.anconawellness.com and I realized there was something important missing on the homepage that required coding. He helped me overnight to achieve what I had envisioned, and the end product just as I visualize it. Thank you and I wouldn't hesitate to work with Bruno again in the near future.
