Try freelance focusing on making MVPs or early-stage products. I’ve always been a jack of all trades, and it never felt like an asset until I started freelancing. Oh, the 3D engine you want me to optimize is Typescript, not C# as advertised or C++ as I was hoping to talk you into? Guess I’m learning Typescript today, ... Oh, your iOS app needs an AWS server set up? Never had to use AWS before (I do mostly apps, not servers, and it was a native iOS project), but some old Linux sysadmin knowledge enables me to jump in and get something running.

You’ll inevitably need to learn something brand new, and you get to pick your clients. After a few successful projects you start looking really appealing as a generalist.

Try Toptal or Moonlight, post on the monthly HN who wants a freelancer post, and reach out locally for clients.
