Worked on the nodejs/api-docs-tooling repository to deliver a new Slugger utility for consistent heading slug generation across documentation. The solution preserved legacy anchor compatibility by restoring alias functionality, ensuring that existing links remained valid while supporting duplicate headings. Refactored the legacy slugger using functional closures to improve maintainability and testability, and integrated the new utility directly into the build pipeline for automated, stable URL creation. Enhanced test coverage with explicit cases for regex replacements, reducing the risk of regressions. The work leveraged JavaScript and Node.js, demonstrating full stack development and testing skills focused on documentation tooling reliability and maintainability.
