E-commerce Full-Stack Developer

Requirements

I am looking for an experienced MERN-focused Full Stack Developer who can move quickly from frontend review to a production-ready backend and payment-ready commerce flows.

• Minimum 5+ years of MERN stack experience (React, Node.js/Express, MongoDB) with strong backend fundamentals.
• Hands-on experience building e-commerce platforms (cart, checkout, orders, user accounts, and product browsing).
• Proven experience delivering admin dashboards with role-based access and practical operational tooling.
• Direct experience integrating Stripe payments.
• Strong understanding of JWT authentication, secure API design, and protecting payment + order flows from edge cases.
• Ability to translate frontend needs into backend contract/API design (clear request/response shapes, consistent error handling, and predictable UI states).
• Clean development practices: version control, maintainable code, and clear documentation for handoff.
• Soft skills we value: ownership, responsiveness, and the ability to break work into milestones. We also expect clear communication and proactive risk identification during implementation.
• Portfolio demonstrating similar commerce or payment-integrated projects.

Note: I will provide the frontend repository link for review(github.com/jose-olivencia235/Ecommerce-Frontend ). Backend work must be built from scratch to match the current frontend architecture.

Job Description

I need you to review the existing frontend and then complete the platform by implementing the missing backend and end-to-end flows.
Here is Github Repository of our Frontend:
github.com/jose-olivencia235/Ecommerce-Frontend

• Perform a code review of the provided React frontend and propose UI/UX improvements that align with the desired backend behavior.
• Design and build the backend using Node.js, Express, and MongoDB, including robust APIs for all core pages and user flows.
• Implement authentication and authorization with JWT (secure routes, role-based access for admin/dashboard).
• Create data models and endpoints for products, collections, cart, orders, wishlists, reviews, and search/filter operations.
• Build an admin dashboard: define features, permissions, and the backend support required (inventory/catalog management, order management, and basic analytics where appropriate).
• Integrate payments with Stripe, including order creation, payment confirmation/webhooks, and failure handling.
• Ensure smooth UX by adding missing frontend/backend coordination such as wishlist actions, reviews workflows, and reliable loading/error states.
• Provide estimates, a milestones-based delivery plan, and clear deliverables as the project progresses.

Budget & Timeline

Time line is within 2 months.

I expect the freelancer to deliver a functioning backend (Node.js/Express/MongoDB + JWT), an admin dashboard plan and implementation, payment integrations for Stripe, and the remaining commerce features: wishlist, reviews, and improved loading states.

Desirable (Preferred)

• Experience with React 18/19 and Vite-based codebases, including performance and UX improvements that enhance loading/error states.
• Experience implementing wishlist/reviews systems with moderation-friendly designs and scalable query patterns.
• Familiarity with search/filter optimization strategies in MongoDB (indexes, query composition, pagination).
• Experience designing admin dashboards with pragmatic components (tables, filters, bulk actions) and secure server-side enforcement.
• Ability to propose improvements beyond the initial scope while staying on schedule and budget.

I am looking for an experienced Full Stack Developer to complete my e-commerce platform. The frontend is already built with React and is publicly available on GitHub. I need someone who can review the existing codebase, identify what needs improvement, and build the complete backend with admin dashboard and payment integration.
