.NET Developer, Tickets Selling System

Client

Our client is one of the regional leaders in the industry and is currently launching a new product—an international platform for ticket sales.

Project overview

The client uses various tools to reach their customers, such as a mobile app, a responsive web application, or communicating with them directly through the call center. The system is big and modular (microservice-based), complying with a number of regulations. We provide APIs for different clients including the biggest Global Distribution Systems (GDSes). We also provide solutions that are labeled by more than half of Train Operating Companies (TOCs) in the UK.

Our client is committed to ensuring that the system will be as modern as possible. It is based on a microservice architecture with the use of continuous integration, where a few hundred components operate independently of each other and can be used as they become available. This increases the modularity of the system and optimizes the use of the services. All components run on AWS.

The backend also includes .NET 8/10, and REST API is actively modernized to Cloud Native solutions (RDS like Postgres, DynamoDB) remove: from MSSQL. The client has a policy to work with the latest technology, and they move to newer versions when they are available.

Team
