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…
Then I managed to get a new project and used it to learn new technologies: modern java, scala, modern js, hadoop, spark, and so on. In the same period I also gave a bunch of tech talks at local meetups. By 38 I had a resume good enough that I basically picked my employer and job of choice, applied and was hired immediately. Recruiters contact me all the time.
I don’t want to say your resume is your problem having not seen it, but for me it definitely was.
