I used to do Wordpress development and the short of it is, it wasn't profitable enough to be sustainable for me. These days, web development is more of a side gig for me and I'm no longer using Wordpress. I don't necessarily need to make a full-time income with it and I'm certainly not looking for high pressure, high stakes projects, but I was wondering where the best opportunities are for freelancers these days and what would be best skills/technologies to learn for those sorts of jobs?

Also, as a more specific side question, are things like Hugo and Jekyll much in demand these days as far as freelance goes?
