Worked on the ARM-software/golang-utils repository to enhance configuration validation by addressing a bug that previously made error messages less informative. Implemented a targeted fix in Go that ensures error messages now include the specific configuration field name, making it easier for users and operators to identify and resolve issues during setup. This change improved the debugging workflow and reduced the time required to diagnose configuration errors, directly benefiting deployment reliability and user experience. Demonstrated skills in backend development, configuration management, and error handling, with a focus on maintainability and traceability by linking the work to a relevant business ticket.
