Have you had experience working with Legacy code?

Yes, I have experience working with legacy code. This usually means dealing with a large codebase without sufficient documentation and using outdated technologies or architectural decisions.

In such cases, it is important to:

• Understand the business logic and key dependencies.
• Write tests before making changes to avoid breaking existing functionality.
• Gradually refactor the code to improve readability and maintainability.

For example, I worked on a project where I had to add new functionality to old React code without using modern hooks, while maintaining the application's stability.
