Tell about your work experience and your last project.

In my experience working as a senior Java developer, I participated in several major projects, including the development of a distributed system for real-time big data processing. In the last project, I was responsible for microservices architecture, used Spring Boot, Kafka for message exchange, and Docker for containerization. I also implemented CI/CD processes using Jenkins and wrote unit and integration tests with JUnit and Mockito.

Example of a simple REST controller in Spring Boot:

@RestController
@RequestMapping("/api/users")
public class UserController {

    @GetMapping("/{id}")
    public ResponseEntity<User> getUser(@PathVariable Long id) {
        User user = userService.findById(id);
        if (user == null) {
            return ResponseEntity.notFound().build();
        }
        return ResponseEntity.ok(user);
    }
}
