" summary

Company uses Free monad + interpreter pattern in Scala (Cats) to separate effects, run DSLs via interpreters, and test with canned interpreters; about 40 active Scala projects and a ~100‑member FP guild. Production uses Future interpreters and swaps S3 for Postgres by writing a new interpreter only, proving low cost of change. Teams with months of Scala deliver purely functional web apps with beginner teams and enjoy swap datastore by writing new interpreter and small monad‑transformer for result handling.
