+## EXPRESSION LANGUAGE IN SYMFONY: Beyond the Framework
+
+<dl>
+  <dt>Description</dt>
+  <dd>Expression Language (EL) is a powerful tool that can be used to dynamically evaluate expressions in Symfony applications. However, EL is often overlooked for use in the business domain.
+
+In this talk, we will explore how EL can be used to:
+
+Increase flexibility and extensibility in your applications
+Avoid the need to redeploy your application every time you need to make a change
+Implement complex business logic in a clear and concise way
+We will also discuss some of the best practices for using EL in the business domain.
+
+Whether you are a Symfony developer who is looking to learn more about EL, or a business analyst who is looking for a way to implement complex business logic in your applications, this talk is for you.
+
+Here are some specific examples of how EL can be used in the business domain:
+- Calculating discounts based on customer loyalty
+- Determining the eligibility for a promotion
+- Validating user input
+- Generating dynamic content
