Tell me about the platform structure and the product you worked on.

The platform structure typically includes several key components: the frontend (user interface), backend (application logic and data processing), database, and integrations with external services.

For example, I worked on an e-commerce platform where the frontend was implemented in React, providing a user-friendly interface for customers. The backend was built on Node.js, responsible for order processing, catalog management, and interaction with payment systems. Data was stored in PostgreSQL.

The product allowed users to search for products, add them to the cart, place orders, and track delivery. A recommendation system and user behavior analytics were also implemented to improve the service.
