Key Responsibilities:

Develop robust, scalable, and secure web applications using PHP (OOP)

Write clean, maintainable, and well-documented backend code

Design and manage MySQL or PostgreSQL databases

Integrate and consume RESTful APIs and third-party services

Work closely with front-end teams for smooth API consumption

Debug and optimize application performance

Handle authentication and session management securely

Implement MVC architecture using frameworks like Laravel / CodeIgniter

Manage deployment and server configurations (Apache/Nginx)

Maintain version control using Git/GitHub

Write unit and integration tests
