Publishing

For world-leading publishers like The New York Times, Chicago Tribune, USA Today, LA Times, Chronicle Herald, and others, we deliver a custom engagement platform consisted of several modules. Each module solves a specific problem in the chain of business management based on a new user, ending with his disconnection from the subscription and building analytics.The major role is played by the data we receive from the customer system. This data in our system is processed, managed, supplemented by analytics, and synchronized back.

The project is dynamic, voluminous and requires skills to work in a changing environment. There is an opportunity to study and apply automation - mix QA or AQA. The product has a large number of integrations with different authorization and circulation systems, payment providers.

We are integrated with systems such as:

Vindicia CashBox;
Spreedly, Braintree, Cybersource, Edgil;
Auth0, Janrain;
Google (SWG, Google Pay, Google Play, AMP, GA);
Facebook;
Apple pay, iTunes.
