.NET Developer, Tickets Selling System

About the Position

DataArt is currently helping develop new features and modernize the IT system of an independent online railroad ticket retailer. The project is a great place to work and grow for Middle engineers due to strong engineering practices (microservices, clean code, extensive unit testing, CI, dozens of production deployments weekly, the Scout Rule, code reviews, and an Agile approach), continuous technical refactoring, and a senior team that is willing to learn and share experience.

About the Project

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 7/8, and REST API is actively modernized to Cloud Native solutions (RDS like Postgres, DynamoDB) from MSSQL. The client has a policy to work with the latest technology, and they move to newer versions when they are available.
