Worked on stabilizing backend metrics collection by addressing error handling in the MysqlHostMetrics component across the planetscale/vitess and vitessio/vitess repositories. Focused on preventing runtime panics by ensuring that when the configuration object (Cnf) is nil, the system returns a safe, empty response rather than failing. This approach involved implementing robust checks in Go, accompanied by comprehensive unit tests to validate correct behavior in edge cases. The changes were delivered across both repositories, promoting consistency and reducing production risk. Emphasized reliability and maintainability through CI-ready updates, demonstrating proficiency in Go, backend development, and automated testing practices.
