I've worked with Aaron several times, and each time he has gone above and beyond what was strictly required, helping me to achieve my goals. Highly recommended!
Aaron was great to work with. He was always responsive to any of my questions, willing to become integrated with our team and was very helpful during the time we hired him. He was also very willing to communicate with our team and share feedback with all of us which was a crucial part of why we hired him. Unfortunately we had to end the contract after one of our customers ended up decreasing the project work load. That is the only reason why Aaron isn't still working with us and it is no fault of his. I would recommend him and hire him again for future work.
I was using MusicCenter on my iPhone 4 on iOS 5 I love your tweaks! First app going on my 4s is PowerCenter Pro, MusicCenter and Faves :p your stuff rocks!
Aaron's work and communication is superb. He not only completes the work successfully, but takes extra steps to help troubleshoot and explain the fixes or features that he's implementing.
