Ecommerce Platform

From idea to a complete ecommerce platform

Designed and built Caravano, a multi-tenant ecommerce platform for creating and managing fully branded online stores. The platform brings together storefronts, products, content, orders, payments, shipping, localisation, and administration in one system.

AI-assisted store and product composers let merchants describe what they want in natural language and turn those descriptions into structured, editable storefronts and product content. The generated result can then be reviewed and refined through the regular platform interfaces.

Built with Next.js, TypeScript, Payload CMS, PostgreSQL, Cloudflare R2, and Stripe, Caravano combines a flexible frontend with a full ecommerce backend, integrated services, and managed infrastructure.
