About the Role

This is a freelance role for a Tendem project. As a Frontend Developer, you'll design, build, and refine landing pages, waitlist pages, promo pages, and small multi-page sites (portfolios, restaurant sites, small business sites, simple online stores), turning client briefs into responsive, performant, polished web experiences.

Key Responsibilities

• Build landing pages, waitlist pages, and promo pages with clear hero sections, CTAs, and conversion-focused layouts.
• Build small multi-page websites (Home, About, Services, Contact, etc.) that follow client requirements and basic information architecture.
• Implement responsive, mobile-first layouts that work cleanly across devices and browsers.
• Integrate forms, email capture, basic analytics, and simple CMS or headless content sources.
• Apply on-page SEO basics (semantic HTML, meta tags, performance, accessibility) so pages are ready to rank and run ads against.
• Evaluate AI-generated frontend output and refine markup, styling, structure, and copy placement to production quality.
• Troubleshoot layout, performance, and cross-browser issues independently.

Requirements and benefits

• At least 3 years of relevant experience in frontend development, landing page production, or website development (required)
• Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, Design, or related fields is a plus
• Candidates should have a strong foundation in modern frontend development, responsive web design, and building high-quality landing pages and small websites. We are looking for specialists who can create polished, conversion-focused user experiences, work confidently with modern frontend frameworks, and refine AI-assisted output into production-ready interfaces. A strong visual eye, attention to detail, and the ability to work independently are essential
• Strong command of HTML, CSS, and JavaScript, including responsive design, Flexbox, and Grid
• Hands-on experience with at least one modern frontend framework (React, Next.js, Vue, Astro, or similar)
• Experience with utility-first CSS (Tailwind) or modern component libraries
• Ability to translate Figma designs or written briefs into clean, maintainable code
• Familiarity with form handling, email capture services, and basic analytics setup (GA4, Plausible, or similar)
• Working knowledge of on-page SEO, accessibility (WCAG basics), and Core Web Vitals
• Comfortable working with simple CMSs or headless content (Webflow, Framer, Sanity, Contentful, or similar) is a plus
• Strong attention to detail and visual taste — pages should look intentional, not generic
• Self-directed work ethic with the ability to deliver complete pages with minimal supervision
• Portfolio of shipped landing pages and/or small websites (required)
• English proficiency: Upper-intermediate (B2) or above (required)
