Why seven areas of expertise? Because I like the number seven and I wanted a seven sided image. So I picked the top seven areas. They are others.
Where is Build? All seven areas involved build.
Don't you code? Yes I do. I can. I have. But most coding that I do now-a-days is customizing, integrating, configuring. Perhaps an additional module here and there. It is rare to find an application that needs to be built from scratch.
