Multi-vendor marketplace platform

01Challenge

A marketplace is not one product but three connected ones: the customer who shops, the seller who uploads stock and works their orders, and the operations team that moderates catalogue, sellers and orders. All three read the same catalogue and order data, and none of them can share a screen. On top of that the market is multilingual — the same product record has to live with its Russian, Turkish and English versions.

02Approach

Catalogue, orders, payments and seller data sit behind one API, and all three panels connect to the same service with different permissions. The seller side runs as a single flow from application form to panel, with sign-in by phone number and verification code. Language support goes beyond interface strings: the category tree, the legal contract pages and the product record itself all change with the language — the seller fills the product card once per language. The seller and customer mobile apps talk to the same API — there is no second data model.

03Outcome

A seller files an application, opens their store, and runs stock, orders, revenue and payouts from the panel or from their phone — purchase conversion and drop-off reasons sit on the same screen. On the customer side the category tree, filters, search, favourites, cart, checkout and order tracking are all live, and operations sees the same data from the admin panel.
