I am amateur and more or less an ignorant in programming domain so what I say doesn't matter much.

Why not a pick a language of choice and write some ambitious framework/library? Like Numpy/Pandas for Python. Maybe a web development framework? That way, there is a reasonable chance your work will be noticed or used. Look Maybe pick Julia and write a library for it. I believe Julia doesn't have as many libraries as Python does.

By the way, as much as I know, all the languages were written by 'old' people. Young people rarely have that much knowledge or experience. They don't even know one language fully well. So age is actually at your side.
