Joking aside, I'm sorry that happened to you and I'm sorry for the people that took over the system I helped to write.
Did Akka; thank goodness that didn't make it to production.
GraphQL: Helped in many ways. Hurt in so many too. In production.
Everything in Actors: State was everywhere. So much pain. In production.
I just use Postgres + RPCs for everything now.
