Frontend EngineerPosition: Frontend EngineerType: Freelance Hourly ContractCompensation: $90/hourLocation: RemoteAbout the OpportunityThis opportunity is for experienced Frontend Engineers and Full-Stack Developers interested in evaluating AI-generated web interfaces and code.The work focuses on comparing AI-generated frontend implementations against real-world reference websites, assessing both visual fidelity and underlying code quality.This is an evaluation-focused role rather than a traditional development position. The key requirement is the ability to identify how a webpage is constructed, recognize technical shortcuts, and provide precise, evidence-based evaluations.What You'll Do- Render a reference webpage and two AI-generated implementations at a 1920×1080 viewport and evaluate which version most accurately reproduces the reference.- Compare visual fidelity across different interface states, including layout, spacing, typography, colors, borders, images, layering, and overflow behavior.- Review the source code of AI-generated implementations and assess HTML structure,



CSS architecture, responsiveness, maintainability, and implementation quality.- Identify technical shortcuts such as excessive hardcoded positioning, unnecessary absolute positioning, poorly structured markup, or image-based recreations.- Test responsive behavior across different viewport sizes and identify layout or usability defects.- Use browser DevTools to inspect elements, computed styles, DOM structure, and interactive states.- Provide specific, evidence-based written justifications explaining why one implementation is stronger than another.- Identify genuinely broken evaluation tasks while distinguishing them from tasks that are simply challenging.Required Qualifications- 3–8 years of professional web development experience, primarily in frontend or full-stack engineering.- Strong hands-on experience with HTML, CSS, JavaScript, responsive web development, and modern frontend engineerin
