Tazj – Fresh Grocery Delivery App (UAE)
Overview
Tazj is a UAE-based, multi-vendor grocery delivery app that connects users with local sellers offering fresh, organic produce, meats, fish, and more—all delivered on the same day at market prices. The platform is unique in its vendor-first experience, where users choose a vendor before browsing products.
This version of the app was a complete rebuild from the ground up, unrelated to the legacy system and developed with modern architecture and scalability in mind. The multilingual system launched with English and Arabic, and was designed to support any number of languages in the future.
