Tell me about your last project, what you did there, what tasks you solved? The most interesting cases.

In my last project, I worked on an order management system for a large retailer. My main task was to develop a backend service in Java that processed orders, interacted with a database, and integrated with external payment systems.

The most interesting cases:

• Implementing reliable transaction processing using Spring Transaction Management to ensure data consistency during failures.
• Optimizing performance for bulk order processing by implementing asynchronous processing with CompletableFuture and message queues.
• Integrating with external payment API systems with error handling and retries to improve resilience.
• Writing unit and integration tests using JUnit and Mockito to ensure code quality.

This project allowed me to deepen my knowledge of the Spring Framework, working with REST APIs, and building fault-tolerant systems.
