Contributed to the typst/typst repository by enhancing developer experience and reliability through targeted backend improvements using Rust. Developed a feature that refines panic message formatting, enabling escape character support in panic strings and removing quotes for improved readability, with comprehensive tests validating these scenarios. Addressed a bug in the evaluation engine by improving error handling for invalid operations on temporary values, resulting in clearer, more actionable error messages. Collaborated closely with co-authors to strengthen test coverage and maintainability. These efforts improved debugging productivity and user-facing clarity, leveraging skills in Rust programming, backend development, error handling, and rigorous testing practices.
