Differentiating factor with my competitors
Jon showed me how to apply many of the concepts about unit testing to iOS. It was the one thing I needed in order to use it everywhere. Jon is one of the few who knows the stuff and knows how to explain it.
My customers value my knowledge about testing and it is always a differentiating factor with my competitors. I owe a lot of it to Jon.
The single biggest influence
Jon approaches software as a craftsman. He takes design and architecture very seriously, to the point of evangelizing, teaching, and influencing those around him to become better at what they do.
In my years as a professional, learning from Jon has probably been the single biggest influence on the way I write software today.
