How Infygen Built a Scalable E-Commerce Platform
A scalable online store — product catalog, cart, secure checkout, payments and order management — engineered to stay fast and reliable during sales spikes.
⚠️ This is a representative case study of a genuine build. Specific metrics, screenshots and client details are placeholders pending final, disclosable data.
The Challenge
An e-commerce platform has to stay fast while browsing large catalogs, keep carts and inventory consistent, and process payments and orders reliably — including during traffic spikes like sales and launches.
The client needed a storefront customers trust, an admin panel to manage products and orders, and a checkout that never loses an order or mishandles a payment.
Our Solution
Infygen built an e-commerce platform with an Angular storefront and admin panel, a Node.js/TypeScript backend, PostgreSQL for catalog and orders, Redis for caching, and AWS for infrastructure.
It covers the full shopping journey: browsing and search, cart, secure checkout, payments, order tracking, and an admin panel for products, inventory and orders.

Technology Stack
Challenges & Engineering
- Catalog performance: frequently-read catalog data is cached in Redis and queries are indexed, so browsing stays fast even with a large product set.
- Consistent orders and inventory: checkout and stock updates were handled carefully so an order is never lost and stock never goes negative.
- Reliable payments: payment handling was designed so a payment is never double-counted and order state always matches payment state.
- Background processing: order confirmations, emails and receipts run on a queue off the request path so checkout stays responsive under load.
