Worked on enhancing gRPC error handling in the square/wire repository by implementing trailer parsing for error responses in Kotlin. Focused on cases where the response body is empty but error details are present in the trailers, ensuring that critical error information is captured and propagated to exceptions. This approach improved the reliability and debuggability of the Wire client in production environments by preventing silent failures and preserving complete error context. The work involved a minimal, targeted update to the Wire runtime, requiring no external API changes, and demonstrated strong skills in API development, error handling, and gRPC protocol integration.
