I am most useful when the problem is consequential, somewhat ambiguous, and not already solved by hiring another pair of hands. I am much more interested in helping determine what should be built, changed, funded, stopped, or understood, and then helping make sure it actually works.
I am probably not the right person if you simply need commodity development capacity or the lowest hourly rate available. There are good options for both, and I am happy to say so on the first call.
