E-Commerce Stack (Next.js, Stripe, Shopify, PostgreSQL, Redis) overview

A modern headless e-commerce architecture using Next.js as the storefront framework with server-side rendering for SEO and fast initial page loads. Stripe handles payment processing, subscription billing, and checkout sessions. Shopify Storefront API (or a headless Shopify setup) provides the product catalog, inventory management, and order fulfillment layer. PostgreSQL stores application-specific data — user profiles, reviews, wishlists, and custom analytics. Redis powers session management, cart state, product recommendation caching, and rate limiting. TypeScript spans the full stack. This architecture suits brands that need custom storefront experiences beyond Shopify's theme system while leveraging Shopify's operational backend. The tradeoff is maintaining two systems — the headless frontend and Shopify's admin — which doubles the integration surface for inventory and order sync.
