This skillset is literally the poster child of HN.

> Yes, I know my skillset is quite generic - heavily JS/Node/React based, with a few years of experience in Python and very light knowledge of some lower level languages (had some passing interest in Go, Rust, no commercial experience to back it up).

Don’t be discouraged, lots of successful places are using this for good reason.

It’s a perfectly valid and respectable way to make a career.
