PROFILE

Yuchao Liang

Yuchao contributed to the swc-project/swc repository by enhancing the SWC minifier’s handling of JavaScript template literals and number formatting methods. Over three months, Yuchao expanded the Evaluator to support static analysis of binary expressions and template literals, introduced a public API for safer identifier resolution, and refactored template string evaluation to handle nested cases and Unicode sequences robustly. Using Rust and JavaScript, Yuchao improved minification accuracy and reliability, reducing output mismatches and runtime errors. The work demonstrated depth in compiler design and backend development, with careful attention to extensibility, test coverage, and safer production deployments for complex codebases.
