ShopZen — Full-Stack E-commerce Platform with Admin Dashboard

Live Storefront Preview — Product grid, real-time inventory alert, cart sidebar
⚠ The Challenge
A growing online retailer was running their store on a generic template platform that couldn't support their custom discount logic, multi-image product variants, or the real-time inventory alerts their warehouse team needed. They required a custom-built solution.
💡 Our Solution
We built ShopZen — a full-stack MERN e-commerce platform with a customer-facing storefront, a seller dashboard, and an admin panel. Features include product variant management, a cart and checkout flow, Stripe payment integration, order tracking, and a real-time inventory alert system.
✓ The Outcome
ShopZen replaced their template platform entirely. The custom discount engine handles all their promo logic. Inventory alerts have eliminated stockouts. Order processing time dropped by 60% with the new admin panel, and the customer checkout experience improved measurably — cart abandonment fell by 35%.

Discovery & Planning
The client came with a detailed list of pain points from their existing platform — primarily around product variants, discount rules, and inventory. We ran a 2-day discovery sprint to map the full customer journey (browse → cart → checkout → delivery tracking) and the admin workflow (product management → order fulfillment → reporting). The data model was designed around products with nested variant arrays, order state machines, and inventory thresholds.

Design & Build
The storefront was built in React with a clean, minimal UI — product grid, filter sidebar, product detail with image gallery, and a multi-step checkout. Redux Toolkit managed cart state with localStorage persistence. The backend handled product CRUD, order lifecycle, and a custom promo/discount engine supporting percentage and flat-rate codes. Stripe handled payment processing. Socket.io powered real-time inventory alerts to the admin panel. Cloudinary managed all product images with transformation on delivery.

Testing & Launch
We stress-tested the checkout flow and payment webhook handling. Discount edge cases (expired codes, minimum order thresholds, stacking rules) were unit tested. The inventory alert system was tested under concurrent order simulation. Full cross-device QA before deployment. Deployed on Vercel + Railway with automated GitHub Actions CI/CD pipeline.

"ShopZen gave us everything our old platform couldn't. The discount engine alone handles scenarios we had to manually manage before. Our team loves the admin panel."
