Worked on the biomejs/biome repository to enhance the reliability of type-aware resolution in Rust-based backend systems. Addressed a bug in the resolver so that packages exposing typed entry points via the main field in package.json are now correctly included, even when the types field is omitted. This adjustment allows type-aware rules, such as noFloatingPromises, to accurately analyze imports and reduces false negatives in type analysis. The solution was implemented with careful attention to backward compatibility, supported by targeted tests and clear commit documentation. Demonstrated skills in Rust, backend development, and package management while improving downstream tooling reliability and maintainability.
