They create dynamic, data-driven web pages and interfaces by integrating front-end components and back-end databases. They handle server-side programming, manage client requests, and ensure seamless interaction between the user interface and server. They often collaborate with other developers to integrate Java-based applications and troubleshoot issues. Additionally, they may be involved in testing, debugging, optimizing code, and implementing security measures. They also often participate in the entire software development life cycle, from requirement analysis to deployment.
