There are many advantages of hiring an Enterprise JavaBeans (EJB) developer, including:
EJBs are designed to make development faster and easier by providing a component-based, platform-independent model for building enterprise applications.
EJBs can be deployed on any Java EE compliant application server, making them highly portable.
EJBs are managed by the container in which they are deployed, meaning that developers do not have to write code to manage concurrency, security, transactions, etc.
The use of EJBs can improve application performance as well since they are designed to be lightweight and efficient.
