A Laravel developer designs, builds and maintains applications using Laravel, a popular PHP framework. They utilize its elegant syntax to develop web applications following the model-view-controller (MVC) architectural pattern. Their tasks include back-end components development, connecting applications with other web services, and integrating front-end elements built by their co-workers into the application. They also ensure the application's performance and responsiveness. Laravel developers often work with databases, use Laravel’s ORM Eloquent, and employ Laravel's tools for testing and debugging. They also maintain code quality, organization, and automatization, ensuring adherence to best practices.
