I'm starting to see the backend/frontend separation as being much less meaningful than it used to be. Plenty of technically client-side code that has incredibly sophisticated data architecture, and server-side code that's focused on responding to events with presentation logic. The most employable people now have strong fundamentals. The worst solutions I see are generally from the "when all you have is a hammer" kind of devs. So if you're looking at specific en-vogue techs that help with that, I'd say TypeScript is leading the charge right now. Apollo is also good, since Apollo shops will love you, people with any graphql will still see it as an asset, and basically everyone cares about web services in general.
