    "displayName": "Saga / Distributed Transaction (Go, Kafka, PostgreSQL, Redis, gRPC, Docker)",
    "description": "A distributed transaction orchestration system implementing the Saga\npattern in Go, where long-running business processes spanning multiple\nmicroservices are coordinated through a sequence of local transactions\nwith compensating actions for rollback. Kafka serves as the durable\nevent backbone, ensuring exactly-once delivery semantics for saga\nstep transitions. Each participant service exposes gRPC endpoints\nfor forward and compensating operations, with PostgreSQL storing\nlocal transaction state. Redis provides distributed locking and\nidempotency keys. Prometheus and Grafana monitor saga completion\nrates and latency. The tradeoff is significant complexity in\ndesigning compensation logic and handling partial failures, but\nthe pattern enables consistent distributed workflows without\ntwo-phase commit.\n",
