Developed and delivered OpenTelemetry Ruby gRPC Client Instrumentation for the Shopify/opentelemetry-ruby-contrib repository, focusing on enhancing observability and traceability for Ruby-based gRPC clients. The work introduced a configurable client interceptor that captures and exports gRPC client requests and responses as traces, supporting peer service name configuration and selective metadata header inclusion. Implemented robust handling for both successful calls and gRPC-specific errors, ensuring accurate trace tagging and error propagation. Leveraging skills in Ruby, gRPC, and instrumentation, this feature enables improved troubleshooting and cross-service correlation, laying the foundation for broader instrumentation across Ruby services without addressing separate bug fixes during the period.
