I don't do that type of analytics, but what I can see is that's it's quite hard to hire a good FE guy.

Backend can be hard as well when looking for specialized stuff like Elixir, OCaml, Scala, Rust, etc. On the other hand, pure Ruby - Python - Java - C++ that's fairly common and not as likely to fetch high salary, since you'd be competing with a larger talent pool.

I've found for FE work, esp for someone with good sense for the visuals, typical off-shore contractors in Asia do not provide the adequate skillset
