Clothify is a production-grade, API-first fashion e-commerce platform featuring a versioned Express.js + MongoDB API (50+ REST endpoints across 12 modules) paired with a feature-sliced React frontend using RTK Query and HTTP-only JWT authentication.
Fashion retailers need variant-level inventory tracking (size + color matrices per product), atomic checkouts that prevent stock race conditions during flash sales, multi-channel verification flows (Email + WhatsApp OTP), and real-time business intelligence dashboards. Off-the-shelf platforms lack the flexibility to handle these fashion-specific requirements without costly workarounds.
We built an API-first e-commerce system with a layered MVC backend (Express.js + MongoDB) and a feature-sliced React frontend. Checkout uses MongoDB sessions to atomically decrement variant-level stock and create orders in a single transaction. Stripe PaymentIntents are reconciled asynchronously via webhooks, while 8+ server-side aggregation pipelines power the admin analytics dashboard.
Engineered from scratch with clean code, scalable architecture, and strict attention to performance.
Checkout uses MongoDB sessions to atomically decrement variant-level stock and create the order in a single transaction, eliminating out-of-stock race conditions.
Server-side PaymentIntent creation within order transactions, reconciled asynchronously via Stripe webhooks to guarantee payment and fulfillment state consistency.
Admin dashboard computes revenue trends, order status distributions, user growth, category sales, and top-selling brands via performant server-side aggregations.
Crypto-token email verification + WhatsApp OTP delivery via Twilio with TTL-indexed auto-expiring documents and server-side Google reCAPTCHA v2 protection.
Fashion-tailored schema supporting multi-dimensional size/color matrix tracking per product, preventing overselling and reducing refund overhead.
HTTP-only secure JWT cookies (eliminating XSS token theft), Helmet HTTP headers, Mongo query sanitization, HPP parameter pollution protection, and RBAC guards.
Clothify delivered transaction integrity during high-volume sales while providing fashion retailers with real-time inventory and sales intelligence.
