  Sellers must be able to list products, set prices, manage inventory, update product descriptions, upload images, and view product analytics like views and sales performance.

  The system must be designed in a modular way, so features can be updated or added without affecting other parts of the platform. Clear logging and monitoring should be in place to track issues.
