I have a gigantic open-source portfolio[0]. I also go to great lengths to make sure that I’m a “known quantity” (like posting frequent exposition on fora like this one). I don’t feel that I have anything to hide. Everyone that has worked with me has found the experience enormously fulfilling.
It’s been quite jarring to see this ignored and treated with disbelief. That’s pretty much exactly the opposite reaction from the one that I would have, but I guess I’m out of touch with the way things are done, these days. I even talked to someone who told me about a friend that had invented some kind of machine learning candidate evaluation system, and relied on that, as opposed to human vetting.
One of my goals is to discourage people that wouldn’t want to work with me. I was a hiring manager for a fairly high-functioning, high-stakes team, and am quite aware of the value of making good hiring choices, which go well beyond simple expertise. Team dynamics are also very important.
I feel that getting a job as a result of misrepresentation is a big mistake, and a recipe for misery. So I don't hide my age, don’t pad my résumé, and make every effort to be as open as possible. If you don't want to work with me; fine. Let's not waste each others' time.
I have always sought to make it easy for people to figure me out. Since I live a fairly good life, and know my way around the playground, I feel that I'm a pretty good bet, but I have no problems if others think otherwise.
One of my favorite Twain quotes is "Let us so live that when we come to die, even the undertaker will be sorry."
