I used to get called a 10x developer, I was also called a rockstar and a ninja and a 100x dev and every other compliment that was hip. Then I hit 30. That type of talk stopped. Then I hit 40. Now I will not be considered for any entry level, mid level, or senior level software dev job anywhere in the United States, despite being very desperate and willing to relocate for anything. Doesn't matter. Too old. I'm suppose…
This guy blows those "workhorses" out of the water. He's a Clydesdale. He literally makes everyone else on the team (including me) look bad in comparison. He's THAT good.
He acknowledges that due to his age, he has to work harder to prove himself. On our current team, he no longer has anything to prove, yet puts in rock star performances day after day after day. I could go on but you get the point. Don't give up!
