Worked on cross-platform enhancements to the Flag Configuration API in the DataDog/dd-sdk-ios and DataDog/dd-sdk-android repositories, focusing on improving request context, backend alignment, and observability. Leveraged Kotlin and Swift to add SDK name and version metadata to flag configuration requests, standardizing payloads for better tracking and debugging. Refactored the FlagAssignmentsRequestBody on iOS to match backend requirements, ensuring consistency across platforms. Emphasized API integration and unit testing to support safer feature rollouts and richer telemetry. The work enabled faster issue diagnosis and improved debugging workflows by aligning request structures and metadata between Android and iOS development environments.
