Functional Design for Reference Architectures
summary
Claims that adopting Scala functional patterns and a reusable codebase yields measurable gains: a reference architecture as code for the Scala ecosystem, applied to a subscription µ-service built with DDD and CQRS boundaries, composes tagless final algebras with interpreters, Kafka event outputs and an effect monad for repositories and testing. The artifact proves faster feature delivery and a substantial drop in bug counts across three releases, shows how tests run against an ID interpreter, and demonstrates which parts actually needed these patterns.
