Nebula Commerce

Overview

Nebula Commerce is a full-stack e-commerce platform built for scale and speed. It supports multi-vendor storefronts, real-time inventory, and a seamless checkout experience powered by Stripe.

Challenges

The main challenge was handling thousands of concurrent sessions during flash sales without degrading performance. We solved this with Redis-based cart caching and an optimistic UI that never blocks on the network.

Tech Stack

• Frontend: Next.js with TypeScript, Tailwind CSS
• Backend: Node.js API with PostgreSQL and Prisma ORM
• Payments: Stripe Checkout with webhook-driven order fulfillment
• Caching: Redis for sessions, cart state, and rate limiting

Outcome

Launched to 10k+ users on day one. Achieved 99.9% uptime during a Black Friday campaign with 3× normal traffic load.
