> I think greenfield development is a young man’s game

Most of my work, these days (and for the last decade), has been “greenfield.” I think that new designs benefit greatly from an experienced hand.

Much of my work remains fairly static, with occasional updates to stay relevant (I retire stuff that I no longer want to maintain), as I do tend to get it right, early in the development cycle, and the stuff that has taken off, has been farmed out to larger (younger) teams, who do a marvelous job of maintaining and extending my original work.

Seconded - greenfield development benefits more than anything else from experience.
