What experience do you have in implementing large-scale projects in PHP?

I have experience in implementing large-scale projects in PHP:

• Developing multi-tier web applications using MVC frameworks such as Laravel and Symfony.
• Optimizing performance through caching, queue usage, and code profiling.
• Integrating with external APIs and services.
• Working with relational databases (MySQL, PostgreSQL), designing data schemas.
• Organizing modular and testable code using PHPUnit.

For example, I participated in the development of an online store, where I implemented a system for managing products, orders, and users, ensuring the security and scalability of the application.
