I would work with Steve again 100 times over without any question. He was fast, dependable, wrote great code, and made a lot of excellent suggestions on both a technical and design level to improve the project. He also found other areas to improve upon the code and suggested simple fixes for many things. Steve is absolutely fantastic and I loved working with him.
