Do you plan to modularize the project when developing an online store?

Yes, dividing an e-commerce project into modules is a good practice that improves the structure, maintainability, and scalability of the application.

For example, modules can be distinguished as:

• Authentication Module — registration, login, session management.
• Product Catalog Module — display, filtering, search.
• Cart Module — adding, removing products, calculating total cost.
• Order Processing Module — entering address, selecting payment method.
• User Profile Module — managing user data.

In Android, you can use architectural components such as ViewModel, Repository, and also organize code into packages and use Gradle modules for large projects.

This division facilitates testing, code reuse, and parallel team work.
