    "displayName": "Scala Akka Microservice (Scala, Akka, Slick, PostgreSQL, Docker, SBT)",
    "description": "A reactive microservice built on Scala and the Akka actor model, providing\nlocation-transparent concurrency and fault-tolerance through supervision\nhierarchies. Slick serves as the functional-relational mapping layer for\nPostgreSQL, offering type-safe query composition. Circe handles JSON\nencoding/decoding with compile-time derivation, while Cats provides\nfunctional programming abstractions like Monad and Traverse. SBT manages\nmulti-module builds and dependency resolution. Docker containers are\nproduced for deployment. The tradeoff is significant JVM startup time\nand the complexity of reasoning about actor mailbox semantics under load.\n",
