Actually Using Haskell!
summary
A minimal web API is coded with Scotty and built with Stack, producing a native executable that serves endpoints, queries and inserts rows in Cassandra via cql-io, and publishes messages to Kafka using hw-kafka-client. Demos compile and run, console and Kafka consumers show the messages, and type-driven checks shift many failures to compile time rather than runtime, so the tooling and libraries actually make Haskell practical for these real world integrations.
