Worked on improving UI consistency and code maintainability across the antiwork/helper and antiwork/gumroad repositories. In antiwork/helper, migrated from a custom popover to a library-based solution and refactored key UI components such as MemberFilter, ColorInput, and SecretInput into reusable modules, reducing duplication and future maintenance overhead. In antiwork/gumroad, performed a comprehensive code cleanup by removing dead code, unused assets, and outdated utilities and hooks, streamlining the codebase for upcoming design migrations. Utilized JavaScript, TypeScript, and CSS throughout, focusing on frontend development, component reusability, and code refactoring to enhance stability and accelerate future feature delivery.
