A real log processing platform that:
Ingests 10,000+ events/sec from multiple sources
Streams through Kafka with exactly-once semantics
Persists to durable storage with rotation policies
Searches via Elasticsearch
Auto-scales on AWS / GCP with monitoring + alerting
Has Dead Letter Queues, idempotency, and retry semantics that don't lie to you
