Worked on the opensearch-project/data-prepper repository to deliver HTTP-based ingestion and export capabilities for traces, logs, and metrics, focusing on scalable and reliable backend data processing. Developed unified HTTP and gRPC service paths using Java, introducing new service management classes and refactoring configuration flows to streamline integration with OTLP pipelines. Enhanced security with authentication on HTTP endpoints and improved observability by adding metrics for error handling. Implemented comprehensive end-to-end tests for HTTP, gRPC, and protobuf requests, and improved code maintainability through modularization and health checks. Emphasized robust API development, HTTP services, and backend reliability throughout the three-month period.
