Worked on the open-telemetry/opentelemetry-collector-contrib repository, focusing on backend development and API integration using Go and YAML. Addressed a critical bug affecting Azure IMDS Metadata header case sensitivity, which previously caused 400 errors and disrupted Azure metadata provider functionality. The solution involved aligning the Metadata header value to the required lowercase format, restoring reliable behavior for dependent Azure resources such as the azure/aks resourceprovider. The fix was validated through automated tests and targeted verification in AKS clusters across multiple regions. This work improved the stability and reliability of cloud integrations within the observability stack for Azure deployments.
