Worked on enhancing observability for GraphQL operations in the open-telemetry/opentelemetry-js-contrib repository by delivering a feature that adds the parent name attribute to resolver spans. This improvement enables more precise traceability and context during performance monitoring of GraphQL requests. The technical approach involved updating the attribute names enumeration, refining resolver span creation logic, and expanding test coverage to validate the new functionality. Leveraging TypeScript, Node, and full stack development skills, the work aligned with OpenTelemetry instrumentation standards and supports faster incident diagnosis. These changes contribute to long-term reliability and data-driven optimization of tracing across complex GraphQL workloads in production environments.
