Worked on the clinia/x repository over two months, focusing on backend development and error handling in Go. Enhanced the kgox package by implementing improved panic logging, capturing both recovered error messages and stack traces to streamline debugging and root-cause analysis during message handling. Addressed error serialization by fixing CliniaError JSON marshalling, ensuring internal error data was not exposed and expanding unit tests to verify correct JSON population. Maintained robust code quality through targeted reviews and continuous integration checks. The work emphasized observability, reliable error handling, and maintainable logging, contributing to faster troubleshooting and improved stability within the clinia/x codebase.
