Senior Next.js (App Router) + Prisma Developer - Multi-Vendor Marketplace Frontend Redesign

We're redesigning the frontend of an existing multi-vendor marketplace platform. The stack includes Next.js (App Router), Prisma, Redux Toolkit, and Tailwind. We need a frontend developer to enhance the user interface and ensure a seamless user experience. The ideal candidate will have experience with responsive design and be able to work independently to deliver high-quality results. What We Need - Frontend redesign/rebuild within an existing Next.js App Router codebase - Integration with existing Prisma schema and data layer (multi-vendor data structures - products, vendors, orders, etc.) - State management using Redux Toolkit - Styling and responsive design with Tailwind CSS - Close collaboration on UX decisions specific to marketplace flows (vendor storefronts, product browsing/filtering, checkout, possibly vendor dashboards) Required Experience - Demonstrable production experience with Next.js App Router specifically (not just Pages Router or generic React) - Real-world use of Prisma as an ORM in a production app - comfortable with schema design, relations, and querying within server components/route handlers - Redux Toolkit in a real shipped product - Tailwind CSS - Prior work on e-commerce or multi-vendor marketplace builds is strongly preferred Please Include in Your Proposal 1. Links to live sites you personally built or substantially contributed to, ideally e-commerce or multi-vendor marketplace platforms - not just design mockups or GitHub repos with no live deployment 2. A brief note on your specific role on each project (solo build vs. team contribution, and which parts were yours) 3. Confirmation of hands-on App Router + Prisma experience, with a short example of a real problem you solved using that combo 4. Your availability and estimated timeline for a project of this scope Nice to Have - Experience with multi-tenant data isolation patterns - Experience with payment/payout flows (Stripe Connect or similar) if vendor payouts are part of scope - Comfort working from existing design files or a partial design system
