2System Architecture & Concurrency Loop
Designing high-throughput event streaming architectures (Kafka/Flink), sub-second geospatial dispatchers, and fault-tolerant microservice meshes.
Commonly reported, not confirmed. Heavy focus on idempotency, rate limiting, and write-heavy data pipelines.

Strong preference for clean modular code, explicit concurrency primitives, and handling out-of-order event streams.

Commonly reported, not confirmed. Derived from open source Uber engineering architecture publications and candidate feedback.
