📢 DataArt is supporting the modernization and development of the IT system for an independent online railway ticket retailer. We hire for the company, not just the project, ensuring ongoing opportunities or paid idle time between assignments.

In this role, you will enhance digital products through data-driven experimentation and analytics. Responsibilities include running large-scale A/B and multivariate tests using tools like Statsig, applying advanced statistical methods such as CUPED and Bayesian Autotune, automating traffic allocation to optimize feature performance, managing feature flagging with gradual rollouts, kill switches, and targeting, and linking feature flags directly to product metrics.
Client:
Our client is a regional leader in the transportation industry, with annual revenue exceeding €100 million, currently launching a new international ticket sales platform.
Project Overview:
The client engages users through a mobile app, responsive web application, and call center. The system is complex and must comply with numerous regulations. APIs are provided to major Global Distribution Systems (GDSes), and solutions are white-labeled by over half of the Train Operating Companies (TOCs) in the UK.
The system is built on a microservice architecture with continuous integration. Hundreds of components run independently on AWS, increasing modularity and optimizing service usage.
