Your cart persistence strategy will determine whether users abandon at checkout or convert—most MERN stacks I audit lose 30% of sessions because guest carts vanish on refresh or fail to merge correctly after login. Quick questions - are you planning to scale beyond 10K SKUs, and do you need multi-currency support for Stripe or just USD? Here is the architectural approach: - REACT.JS + NODE.JS: Build a token-based auth flow with httpOnly cookies and refresh-token rotation to prevent XSS attacks while maintaining seamless UX across guest-to-user transitions. - MONGODB INDEXING: Design compound indexes on product catalog (category + price + stock) and implement aggregation pipelines that keep search under 100ms even at 50K products. - STRIPE INTEGRATION: Implement idempotent webhook handlers with retry logic and database transaction locks so duplicate payments never occur during network failures or user double-clicks. I've built 4 production e-commerce platforms processing $2M+ annually, including one that scaled from 500 to 40K daily users without rewriting core architecture. Let's schedule a 20-minute call to walk through your schema design and payment-flow edge cases before you commit to a build.

I’d keep this primarily MERN, with MongoDB for catalog/customer/cart data and only introduce SQL if reporting or transactional requirements clearly justify the extra complexity. The two priorities would be scalability and maintainability. I’d structure React into reusable commerce components, keep Express services separated around auth, catalog, cart, checkout and orders, and add proper indexing for product lookup and order queries. Stripe or Razorpay would be integrated with server-side verification, webhook handling and idempotency so payments remain reliable under retries and failed callbacks. I can handle architecture, responsive frontend, authentication, guest-to-user cart persistence, checkout, admin/order flows, automated tests, ESLint/Prettier, Git workflow, cloud deployment and README documentation. Real-time inventory and a lightweight analytics/admin layer can be added cleanly if included in scope. A relevant project is MofiBasket, a custom e-commerce platform with stock management, purchasing, delivery tracking, coupons/promotions and multi-currency support. Estimated timeline: 5-7 weeks for a production-ready V1 including testing and deployment.

@erdavinder2307

Hi, You said you're ready to kick off and want someone from architecture through deployment. Here's where I'd disagree slightly with your stack, and why it matters for e-commerce specifically. ON MONGODB VS SQL You've listed MERN but said you're open to pragmatic SQL. For an online store I'd argue for PostgreSQL, and the reason is orders rather than products. A catalogue is fine in MongoDB — documents with varying attributes suit it well. But checkout is a multi-table transaction: decrement stock, create the order, record the payment, write the ledger entry. If any step fails, all of it must roll back. In Postgres that is one transaction. In MongoDB you're either using multi-document transactions (which work, but negate much of the reason people choose Mongo) or writing compensating logic by hand and hoping. Overselling and orphaned orders are the two bugs that cost real money in e-commerce, and both come from exactly this. Your reporting requirement points the same way — joins across orders, customers and products are what SQL is for. If you prefer to stay on Mongo I'll build it well there and use transactions properly for checkout. But you asked me to justify the choice, so that's my honest recommendation. THE PARTS THAT ACTUALLY DECIDE QUALITY Cart persistence across guest and logged-in states. The moment a guest with items logs in, their session cart must merge with any saved cart rather than replace it. Get this wrong and users silently lose items, which shows up as abandoned checkouts you can't explain. Payments. Razorpay if your market is India, Stripe otherwise. Either way: the order is confirmed by the webhook, not by the browser redirect. Users close tabs, networks drop, and a payment can succeed while your frontend never hears about it. Webhook handling must be idempotent because both providers retry. Stock. Reserve at checkout with a short expiry rather than decrementing at payment confirmation, or two customers buy the last unit within the same few seconds. Indexing. Compound indexes on the actual filter and sort combinations your catalogue uses, not one index per field. This is the difference between a store that stays fast at 10,000 products and one that doesn't. ON HOURLY Hourly suits this well and I'd work in visible increments — a deployed environment you can click through from the first week, not a reveal at the end. My rate is inside your stated band. I'll give you an estimate per feature before starting it, so the total never surprises you. Rough shape: catalogue and admin ~40h, auth and cart ~30h, checkout and payments ~35h, order management ~25h, polish, testing and deployment ~30h. Call it 150-170 hours for a production-ready v1, and I'd rather set that expectation now than discover it together in month two. QUESTIONS 1. India or international? It decides Razorpay vs Stripe, and tax handling. 2. Roughly how many products, and do they have variants (size, colour)? Variants materially change the schema. 3. Do you have designs, or is UI direction part of this? 4. Who manages the store day to day — how much admin tooling do you need in v1? — Davinder, Solidev Electrosoft

The important part here is getting cart, checkout, payments, and inventory state to stay consistent under real usage—not just building the screens. I’d use React + Node/Express with MongoDB for the main store, adding SQL only if reporting or transactional needs justify it. The backend would use clear service boundaries, indexed product/order queries, secure auth, guest + logged-in cart persistence, and Stripe or Razorpay with webhook-based payment confirmation so order status cannot depend on the browser alone. I’d also include automated tests for the critical flows, ESLint/Prettier, deployment, README setup docs, and Lighthouse-focused frontend optimization. A production-ready MVP should take roughly 5–7 weeks depending on admin and inventory scope. Do you already have the product/catalog structure and shipping rules defined?

Hi, I read the full spec MERN-based e-commerce with persistent guest/logged-in cart, auth with password reset, Stripe/Razorpay checkout, indexed schema for fast catalog/checkout under load, automated test coverage, and a deployed demo on Render/Vercel/AWS. I have 8+ years of real-time IT experience in full-stack development, with 5-6 years hands-on in React. My core backend depth is .NET Core/SQL Server rather than Node/Express/MongoDB, though I'm comfortable delivering in the MERN stack as specified the architecture (clean API layer, indexed schema, auth flow, payment integration) is the same either way. My approach: component-based React frontend with Tailwind, RESTful Express API with clear separation of concerns, MongoDB schema indexed for catalog/checkout performance, JWT-based auth with password reset, and Stripe/Razorpay wired into a tested checkout flow. I'll cover critical paths (auth, cart, checkout) with automated tests, keep ESLint/Prettier clean, and deploy a working demo on Vercel/Render for you to test end-to-end. Most relevant recent work: e-commerce platforms with similar cart/auth/payment flows across multiple business domains. Timeline estimate: 10-12 days for a production-ready first release. Akshay B
