**Project description**
Our client is young, still one of Israel's fastest-growing digital content companies that achieved great success in data-driven traffic analysis.

Together, we're building a platform that takes traffic analysis to the next level by enabling users to configure custom reports with multiple tabs, various filters, and metrics sliced over different dimensions. A/B tests and multiple compare modes encourage data-driven improvements, and snapshots allow re-evaluating historical decisions anytime.
 
The platform has been developed by LeanyLabs from scratch for over a year now. For months, it has been the primary tool for gathering valuable insights from the client's data. Now it's time to extend the functionality by bringing sophisticated AD management directly into the platform. 
 
The project is built on TypeScript with React, Redux, Material UI, and other libraries. It has a custom high-performance calculation engine that does all the heavy lifting in a WebWorker thread and provides the main UI with clean data. The client's team takes care of the back-end and provides new front-end features and designs.
