Is excellent if wanna do development, but why not apply your experience instead? Also in all this 10 years you have build some contacts to get your foot in.
I know that accounting and crud apps are not "sexy" and boring.
But you know what is worse and more boring?
Using js!
Jah, sorry, I can't resist.
But honestly most "front-end" work is not amazing at all.
Maybe building visualizations, charts and stuff like that. But pages and apps in front-end is alike build forms, but harder, more complicated and with less performance than native code.

I'm in the process of build a point-of-sale app, and I will envy to have you background instead, or have a partner with that skills.
So, I'm telling you:
You have valuable skills that are higher than Js. Js/html/css is just a tool (that pay, because the front-end work have become more crazy and requiere more effort triying to be somethings is not made for), but in itself not become yet-another-front-end-dev when you already have a better position to offer.
