Modern Responsive React Website Build

I’m ready to have a fully-functioning website built with React.js, JavaScript, HTML, CSS, and Tailwind CSS. The design must be modern, clean, and responsive so it feels seamless on desktop, tablet, and mobile screens.

Scope and features
• Three core pages—Home, About Us, and Contact—styled consistently with my branding assets that I’ll supply.
• Forms: a contact form, newsletter signup, and a feedback form, all validated on the client side and wired to the appropriate backend or service endpoint.
• API work: integrate a payment gateway for future transactions and connect social-media functions such as live feeds or share buttons.
• Reusable React components and mobile-friendly navigation to keep the codebase maintainable and ready for new sections later on.
• Fast-loading, optimized code that follows best practices in accessibility, SEO, and performance.
• Basic deployment support—guidance or scripts to push the finished site to a platform like Vercel, Netlify, or my own server.

Acceptance criteria
1. The site renders correctly on the latest versions of Chrome, Firefox, Safari, and Edge across common breakpoints.
2. All three forms submit successfully to the specified endpoints and display confirmation or error states.
3. Payment gateway and social-media integrations function in a test environment without console errors.
4. Lighthouse performance and accessibility scores above 90 on desktop and mobile.
5. A concise README explains project structure, environment variables, and how to run, build, and deploy.

I’ll provide copy, images, and any branding guidelines; you deliver the complete source code, build pipeline, and a live deployment link so the site is production-ready from day one.
