I was 35 when I had been working a decade on a large enterprise product built on legacy tech: a legacy php framework, a legacy js framework, and desktop apps built with delphi. My job prospects were not great. Recruiters did not reach out to me.

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.
