Developed and delivered SQS Publish Metrics Monitoring for the numaproj/numaflow repository, focusing on enhancing observability and operational insights for backend systems. The work involved instrumenting Amazon SQS publish operations in Rust to capture detailed metrics, including success and failure counts as well as publish latency. By integrating these metrics, the solution enables teams to monitor SQS publishing performance, identify issues more rapidly, and optimize data flows based on real-time operational data. The implementation leveraged AWS SQS, backend development expertise, and metrics instrumentation, resulting in improved visibility and faster incident response without introducing any bug fixes during the development period.
