Implementé la funcionalidad completa de creación y consulta de transacciones siguiendo Clean Architecture.
Cada transacción se valida con reglas básicas de anti-fraude:
Transacciones mayores a 1000 se marcan como rejected.
El resto se marcan como approved.
Integré Kafka para publicar eventos de creación de transacciones y para consumir la respuesta del microservicio de validación.
Uso de Prisma como ORM para persistencia en PostgreSQL.
Estructura modular: domain (entities, use-cases, repositories), infra (DB, Kafka), api (controllers, routes).
