Project overview

Our client develops client-tailored solutions to acquire mobile users and maximize their value for brands worldwide.
Their goal is to lead the industry in innovation through an ever-changing mobile landscape.
They align with their clients’ success by embracing their individual performance goals and operational constraints, with the use of our app expertise to achieve profitable acquisition goals.

Our client develops a tracking and measurement platform, which measures the adds being shown and the performance of users downloading the apps, using the apps, and making purchases, and also measures the media buying itself, its cost, and what is the income of apps users. The system works on hundreds of campaigns running simultaneously; it helps account managers to improve campaign performance.
Their platform analyses vast amounts of mobile ad data, among native, in-app, and mobile web sources, optimizing towards relevant post-install metrics such as user LTV, ROAS, and multi-day retention.

There are 2 parts of the system:
1. CMS which is used internally for account managers, where they can manage the campaigns, generate reports, where they control and monitor all the activities.
2. The core platform, which is a very complex, high-scalable system and runs on a lot of servers. They use a lot of advanced tools and there will be a lot to learn here and need to design a lot of “”triks”” to be able to increase the performance of a platform – it’s a big and exciting challenge from a technical perspective.
