RetailHub Commerce Platform

A retail group wanted to launch a marketplace able to compete with established platforms on speed, catalogue depth and vendor tooling.

Peak traffic, tens of thousands of SKUs from independent vendors, inconsistent product data and a checkout that had to be fast on low-end mobile devices.

A headless Next.js storefront on top of a Node.js commerce API, Elasticsearch-powered search with vendor-aware ranking, and a vendor portal for inventory, pricing and fulfilment.

Search first. The catalogue, filters and product pages were designed around how people actually look for things, with recommendations kept honest and unobtrusive.

Edge-cached storefront, event-driven order pipeline, Elasticsearch for catalogue and recommendations, MongoDB for flexible product data, Stripe for payments and payouts.

Load-tested against projected peak from the first sprint; the checkout was rebuilt twice based on real device data before launch.
