• Engineer service-to-service communication patterns with guarantees for exactly-once delivery, retry logic, dead-letter queues, and telemetry, ensuring end-to-end observability
• Strategically separate write-heavy and read-heavy flows through API gateways and asynchronous processing backed by stream and cache layering
• Guide teams on when to choose NoSQL vs. relational DBMS based on access patterns, consistency requirements, and schema volatility
