I have a decade of checkins and mineable Git data.
I have solved every single problem that I've ever encountered; whether technical or human (I was a manager for a long time).
I have convinced skeptical, conservative, empirical Japanese managers to fund and support development strategies, based mostly on their confidence in me, and my Integrity.
I have hundreds of pages of articles I've written in Medium and my own (multiple) sites.
I have multiple sites that I have designed, and hundreds of pages of instruction, along with entire courses and presentations.
I can trot out a long line of personal and professional references that include CEOs, VPs, lawyers, doctors, consultants, politicians and other engineers, all of whom will sing my praises to the stars -on the record.
A big reason for that, is the reason I'm not extremely well-known (outside of a certain narrow demographic). I have done most of my engineering over the last decade in Service and open-source projects that aren't about making money; but helping others.
However, when I say this, the answer I get is "IF what you say is true..."
Why the hell would anyone make a claim like that without backup? That's crazy.
OF COURSE I can back it up. My SO Story is a mile long, with links to everything.
Damn straight, there's folks better than me at pretty much any branch of what I do, but I know few that can offer the depth of knowledge across the spectrum, like I can.
AND I CAN PROVE IT.
But you'll make your decision based on a half-hour, fifty-line binary tree test that a college student would ace better than me.
I want to see lawyers do legal briefs as part of their interview. I want to see doctors do "trial surgeries." I want to see HR managers do "how would you handle this?" tests as the ONLY variable in their hiring process, while having their portfolios ignored.
After a few months of this crap, I just gave up, and started my own gig. It's working well, but slowly.
I would have been fine, taking a low salary, if the work interested me. My retirement's set. I have a couple of companies that I can use to keep my toys going.
But good luck with the "Draw Spunky" matchbook tests. I'm sure that you'll get top-shelf talent, that way.
