    network traffic, or data. 
* Advanced knowledge of Go, including concurrency, memory management, 
    profiling, testing, and performance optimization. 
* Strong knowledge of partitioning, replication, eventual consistency, 
    idempotency, delivery guarantees, retries, failure handling, and 
    graceful degradation. 
* Extensive experience with Apache Kafka or a comparable 
    event-streaming platform.
