Worked on the DataDog/datadog-agent repository to deliver unified gRPC status code propagation for trace metrics, focusing on improving the accuracy and consistency of trace data. Implemented the propagation of rpc.grpc.status_code and rpc.response.status_code from OTLP spans into Datadog spans, refactoring the logic into the trace semantics registry to support conditional fallbacks and reduce coupling with the transform layer. Used Go for backend development, API design, and comprehensive unit testing. The work aligned with OpenTelemetry semantic conventions, enabling more reliable incident triage and observability across environments by ensuring consistent status encoding for both OTLP and native traces.
