E-Commerce Backend
Scalable e-commerce API with product catalogue, cart, orders, payment gateway hooks, and inventory management.
- Node.js
- Express
- PostgreSQL
- REST API
The Problem
E-commerce products needed a solid API for catalogue, cart, orders, payments, and inventory without a monolithic CMS.
Tight coupling between storefront and data layer made iteration slow.
Tech Stack & Architecture
Node.js / Express REST API backed by PostgreSQL for products, cart, orders, payment hooks, and inventory.
Boundaries keep payment provider details behind service modules so gateways can change without rewriting routes.
Key Results / Business Outcome
Built a scalable e-commerce backend pattern ready for storefront and admin frontends.
Catalogue and order flows are API-first and testable independently of UI.
