Worked on code quality and maintainability across two open-source repositories, focusing on both JavaScript and HTML. In stdlib-js/stdlib, addressed ESLint-driven linting issues by relocating the copyLocationInfo function to comply with code standards and updated the pkgTree documentation to accurately reflect its return value, improving onboarding and reducing developer confusion. For OWASP-BLT/BLT, removed a deprecated HTML template used for editing standalone lectures, streamlining the codebase and eliminating unused components. These efforts targeted technical debt and improved future development velocity, demonstrating a methodical approach to code linting, documentation accuracy, and front end development using JavaScript and HTML.
