During May 2025, Linghuchong focused on backend development and code refactoring across the grafana/prometheus and oasisprotocol/oasis-core repositories. In grafana/prometheus, Linghuchong streamlined performance by refactoring logic to use Go’s built-in max and min functions, reducing conditional complexity while preserving existing behavior. For oasis-core, Linghuchong improved developer documentation by updating comments in runtime_host.go to accurately reflect function names, clarifying intent and easing future onboarding. The work emphasized maintainability and readability, with careful attention to not introduce functional changes. Linghuchong’s contributions demonstrated depth in Go, code refactoring, and documentation, addressing both code quality and developer experience within a short timeframe.
