Brave New World, tales of PureScript and Haskell in production

on YouTube ↗29m

" summary

A payments team moves from typelevel Scala to a stack that starts with PureScript -> Haskell migration, using Nix mono-repo, Terraform and AWS Lambda serverless for deployment, then drops PureScript and serverless after heavy wrapper maintenance, slow parallel CI and cold starts. One app rewrites in a week, production Haskell services total about 10,000 lines of Haskell, give fast cold-start-free performance, mature libraries, and shorter ramp-up (3–4 weeks) versus months for purely functional Scala.
