React Developer to Build & Launch 40-Page Fintech Website on Vercel (Designs Ready)

We are looking for an experienced developer to turn a complete set of 40 finished page designs (built in Claude Design) into a fully functioning, cohesive, SEO-optimized website and host it on Vercel. The designs are done. Your job is to build the real site from them, make it consistent, and launch it. What you're delivering: A live, fully working website built from our 40 provided page designs, hosted on Vercel, with every page functional, every image optimized, and SEO properly set up across the whole site. Scope of work: * Take all 40 page designs we provide and build them into a single cohesive React (Next.js recommended) website. Unify any small inconsistencies into one consistent design system with shared colors, fonts, spacing, buttons, headers, and footers. * Build reusable components throughout — one global navigation menu and one footer used across every page, plus a shared component library so the site stays consistent and is easy to update later. * Set up clean URLs and a logical site structure. Organize all 40 pages into a clear sitemap with clean, readable URLs. We will provide the page list and can help decide the structure. * Optimize every image. Compress and properly size all images, use modern formats like WebP/AVIF, add descriptive alt text to each one, and make sure the site loads fast on both mobile and desktop. * Handle full SEO integration across all pages. This includes a unique page title and meta description for every page, proper heading structure, schema markup appropriate for a fintech/financial services business, an XML sitemap and robots.txt file, Open Graph and social share tags, canonical tags, and strong page speed with good Core Web Vitals and Google PageSpeed scores. * Ensure each page looks and works correctly on phones, tablets, and desktop. * Host the site on Vercel. Deploy the finished site and connect it to our domain. Set up the domain on Vercel with automatic HTTPS/SSL, and provide the GitHub repository so we own the code. * Handle basic integrations. Wire up our contact/lead-gen forms and connect any existing scheduling or onboarding links to the appropriate call-to-action buttons. * Complete QA and launch. Test every page and every link before going live, fix anything broken, and confirm the site is fully live and working on the real domain. What we'll provide: All 40 finished page designs exported from Claude Design as HTML or a zip file, the full page list and content, domain and DNS access, and brand assets. What we're looking for: * Strong experience building and launching React/Next.js websites. * Hands-on experience deploying to Vercel specifically. * Proven SEO implementation on real sites with examples. * A good eye for design consistency. * Clear communication so you can work from provided designs. To apply, please include: 1. Examples of similar multi-page sites you have built and launched. 2. Your experience with Vercel hosting specifically. 3. Your estimated timeline and total fixed price for the full project. 4. Any questions you have about the scope. This is a fixed-price project. We prefer to work with someone who can own it end to end and deliver a finished, live site. Please start your reply with the word "ROOTCAUSE" so we know you read the full post.
