Implement queue-based processing for asynchronous workflows, particularly for high-volume order and inventory operations.

Use observability tooling to monitor integration health, identify bottlenecks and maintain SLA compliance.
-
Contribute to engineering standards through code reviews, pair programming and knowledge sharing.
