Nexus E-Commerce
Headless storefront with ultra-fast page loads and Stripe checkout.
What is Nexus E-Commerce?
Headless storefront with ultra-fast page loads and Stripe checkout.
The problem we solved.
The client's Shopify store was generating six-figure revenue but hitting hard limits: slow mobile load times were tanking conversions, the template was impossible to customise, and the monthly bill was climbing as they added apps. They wanted full ownership of their storefront.
How we tackled it.
We advocated for a headless architecture from day one. By decoupling the frontend (Next.js) from the content/commerce layer (Sanity + custom backend), we could build exactly the UX needed without template constraints. ISR handles catalogue pages so even a 10,000-SKU store loads instantly.
What we built.
Nexus is a headless store with every page statically generated and revalidated every 60 seconds. The checkout flow is a seamless single-page experience with real-time inventory checks before payment is captured, eliminating overselling.

How it's built.
Next.js frontend on Vercel with ISR, Sanity as the product CMS, lightweight NestJS API for cart/order/inventory logic, PostgreSQL for transactional data, Stripe and Razorpay for payments. Webhook handlers update order status in real time as payment events arrive.

Outcomes & impact.
Page load time dropped from 4.2s to 0.8s. Conversion rate improved by 23% in the first month post-launch. The client eliminated significant monthly Shopify app fees, recouping the build cost in under 5 months.
