Overview

Jmaa (jmaa.sa) is a Saudi group-buying marketplace: shoppers team up on the same SKU so everyone benefits from a lower group price once the pool fills—positioned as “Buy together. Save more.” The storefront showcases electronics and more, with clear regular vs Jmaa pricing and Tamara installment messaging. On the engineering side I contributed across NestJS services and Next.js UI: payment integrations (including NowLater, Paymob, Amwal Tech), refactors, and critical bug fixes to keep checkout and group flows reliable at scale.

Highlights

  • Group-buy model: join/create groups, tiered pricing when the pool fills
  • Featured catalog (e.g. electronics) with regular vs group price UX
  • Multiple payment gateways & installment journeys (Tamara messaging on PDP)
  • Full-stack delivery: NestJS APIs + Next.js storefront
  • Reliability work: refactors and production bug fixes at scale
