1. Identify code smells (long methods, nested conditionals, etc.).
2. Write or ensure existing tests cover the code to be refactored.
3. Choose a suitable refactoring technique (e.g., Extract Method, Replace Conditional with Polymorphism).
4. Apply the refactoring technique in small, focused steps.
5. Run tests after each change to ensure no functionality is broken.
6. Commit changes frequently with descriptive messages.
7. Review the diff to confirm behavior hasn't changed.
8. Repeat until code is clean and maintainable.
