I was just in an exact situation that called for something like this. About a month ago, I was trying to implement a collaborative text editor for a freelance client. This was my first time working in the CRDT/conflict resolution space, and I was completely unprepared for how complex it was.

I was using a few open source packages - TipTap, YJS, ProseMirror - but I had a particular use case that the docs simply didn't address (long story). It was the kind of help that would really require at least an hour sit-down with a very experienced developer to brainstorm with me on a solution, but there's not an obvious marketplace for that kind of touchpoint.
