dustinsand/hex-arch-kotlin-spring-boot

This system is a voter management service that provides endpoints for registering, looking up, and verifying voter eligibility. It is built on a hexagonal architecture, exposing functionality through both standard Spring WebFlux and reactive Kotlin Flow REST APIs, as well as an AWS Lambda function. The backend decouples application logic from infrastructure by using ports and adapters for H2 database persistence, asynchronous RPC calls for eligibility checks, and in-memory storage.
