Which version of rails?

Did you work in rails for a year, then rewrite?

How long did the rewrite take?

Was it a rails monolith - server side rendering and no api?

Was the database schema good - did you keep it for the rewrite?

Was it a good fit for react?

That said, I've encountered a solid number of Rails projects that have been dumpster fires because their devs didn't follow conventions AND had horrible modeling/schema issues.

(Example: let's create our own job system that's many times worse than Active Job for no real reason...)

The other recurring thing that I see come up a lot with Rails projects is that nobody can really agree on where to put their business logic for anything complex.
