Worked on enhancing observability for the Zetaclient component within the zeta-chain/node repository by standardizing its logging system. Focused on refactoring the use of zerolog in Go, replacing Msgf with Msg to ensure consistent log message formatting. Introduced a convention of starting log messages with lowercase characters and defined constants for log fields, which improved both readability and maintainability. The changes aimed to streamline debugging and support future codebase scalability. Emphasized code standardization, logging best practices, and refactoring as core skills throughout the process, resulting in a more uniform and developer-friendly logging infrastructure for the project.
