I have a similar background, but I started my own shop. More people asking for web and mobile applications than embedded ones, so for the "how" part, I stumbled into it. As for enjoyment, it's all good except that javascript and its ecosystem are a trash fire. Not such a great language to begin with, then add all of the variants and tooling (node/browser, ES3/5/6, babel, npm, yarn, typescript, webpack, grunt, etc, etc), and the fact that it seems to change every day, just... ugh. I'd take some poorly-documented embedded C API like Nordic's any day of the week over the JS ecosystem.
