Developed and delivered a new Azure Event Hubs Application Metrics Ingestion feature for the opentelemetry-collector-contrib repository, expanding the metrics pipeline to support parsing AppMetrics forwarded from Application Insights. The implementation in Go enhanced the metrics unmarshaler to handle multiple resources within a single payload by appending attributes per record, and introduced an optional average aggregation capability. Comprehensive end-to-end tests were added to validate resource and AppMetrics parsing, with integration verified in Azure environments and export to Prometheus remote writer exporter. Documentation scaffolding was prepared to support rollout and future improvements, demonstrating depth in backend development and cloud services.
