Efficient e-commerce system

Context

The client runs a chain of stores across several European countries. It has an e-commerce system that handles orders and purchases in local stores, and that system is made up of many separate services.

Problem

The client wanted to widen its assortment with a marketplace where suppliers add their own offers. The new product had to be fully integrated with the existing system and keep all of its functions. Performance mattered a great deal, because an enormous number of orders is processed every day.

Solution

We built a fully configurable marketplace with advanced search and a supplier panel. After studying the domain and the logic of the existing system in depth, we integrated with it mainly over REST APIs and SFTP, without changing how it already worked. The whole product was optimised for a very high daily order volume. Payments run through PayU.

Outcome

The client gained a product that widened its assortment, which brought more customers and more orders.
