Worked on backend stability for the einride/sage repository, focusing on improving error reporting rather than introducing new features. Addressed a bug in Go that corrected the order of arguments in error logging, ensuring that received and expected argument counts are accurately reported. This change enhanced observability and made debugging more efficient by providing precise diagnostic information. The work involved reinforcing code-quality standards around error handling and documenting the updates for future maintainability. By prioritizing the reliability of error reporting paths, contributed to a more robust backend system, leveraging Go and backend development expertise to support ongoing codebase stability.
