Worked on enhancing distributed tracing capabilities for the valkey-io/valkey-glide repository, focusing on observability and cross-language reliability. Implemented OpenTelemetry tracing improvements by adding external span context support and refining tracestate validation to comply with W3C standards. Addressed interoperability by updating both Go and Rust FFI layers, ensuring consistent tracing behavior across language boundaries. Improved code maintainability through style refinements and stricter validation logic, reducing integration risks and supporting faster incident response. The work leveraged Go, Rust, and OpenTelemetry, resulting in clearer, standards-compliant telemetry and more robust backend tracing infrastructure without introducing new bugs during the development period.
