Tell me about the product you worked on at Magnit.

At Magnit, I worked on a system for managing inventory and logistics, which allowed optimizing supply and storage processes. The main task was to integrate various data sources and automate real-time stock updates.

The implementation used a Java stack with Spring Boot, ensuring reliability and scalability of the service. An important part was building efficient algorithms for processing large volumes of data and ensuring high system availability.

Example code for updating stock levels:

@Service
public class InventoryService {
    @Autowired
    private InventoryRepository repository;

    @Transactional
    public void updateStock(String productId, int quantity) {
        Inventory inventory = repository.findByProductId(productId);
        if (inventory != null) {
            inventory.setQuantity(inventory.getQuantity() + quantity);
            repository.save(inventory);
        } else {
            repository.save(new Inventory(productId, quantity));
        }
    }
}
