How do you feel about supporting legacy systems?

Supporting legacy code is an important and often necessary part of work, especially at the senior level. I see it as an opportunity to understand the project's history, identify weak spots, and gradually improve the codebase.

In working with legacy code, it is important to:

• Understand the business logic embedded in the existing code.
• Write tests for critical sections to avoid regressions.
• Refactor the code gradually without breaking current functionality.
• Document changes and discuss plans for improvement with the team.

This approach helps maintain product stability while simultaneously improving code quality.
