Cassandra Administrator, Online Retailer

Our client is one of the biggest online retailers worldwide. DataArt specialists help develop and support its services. We have helped the company to create web-portals and mobile apps, delivery control systems, staff management tools, data storage and much more.

Modern IT-systems have allowed the company to increase the amount of its customers to over half a million. Retail provides a yearly profit of around ?1 billion. But our client is determined to earn even more by reselling the technological tools that have led them to their success.

Based on the new IT-infrastructure and the experience of its modifications, the company is working on developing a cross-functional system that will be able to fit the interests of other companies that are interested in acquiring such systems. DataArt provides consultation and development of the software for the client in both areas of their activities: online sales and creation of the cross-functional retail platform.
