Worked on the dora-rs/dora repository to address a logging issue in the CLI tool, specifically ensuring that the dora run command correctly respects the RUST_LOG environment variable. Used Rust to implement a robust solution that defaults to the 'info' log level when RUST_LOG is unset, improving consistency across both local development and CI environments. Focused on maintainability by delivering a targeted fix with minimal risk, thoroughly validating changes through local and CI testing. Demonstrated skills in CLI development and logging, prioritizing reliable debugging workflows and clear log management without introducing unnecessary complexity or feature changes during the development period.
