Description

  • Audit AI explanations for layout and styling solutions to ensure the reasoning is technically sound.

  • High standard for clean, semantic markup and maintainable CSS, including BEM methodology, design tokens, and modern CSS standards.
  • Expert mastery of HTML5 and CSS3/4, including custom properties, animations, and modern layout systems.
  • Extensive experience with Tailwind CSS, SASS/SCSS, or CSS Modules, and familiarity with component-driven design systems.
  • Proficiency with browser DevTools, accessibility auditing tools such as axe and Lighthouse, and cross-browser testing platforms.
  • Background in Software Engineering or Frontend Development.
  • Ability to complete a 10- to 15-minute test to assess skills, if invited.
  • Preparedness to complete paid tasks that require one hour of uninterrupted work.

Benefits
