PROFILE

Grzegorz Wyszyński

Worked on the open-telemetry/opentelemetry-go repository to enhance HTTP/2 transport resilience, specifically addressing failures related to GOAWAY signals during trace export. Delivered a targeted bug fix in Go that preserves HTTP request bodies across redirects by implementing the standard library’s GetBody method, ensuring reliable body re-sending when redirects occur. Developed and integrated comprehensive tests to verify body preservation, reducing the risk of regressions in HTTP/2 environments. Collaborated closely with peers to strengthen the HTTP client’s reliability under challenging transport conditions. Demonstrated skills in backend development, API development, and testing, focusing on stability and correctness in distributed tracing workflows.
