Do you have experience in refactoring code?

Yes, I have experience in refactoring. Usually, refactoring includes:

• Improving code readability: renaming variables, functions, simplifying logic.
• Breaking down large functions into smaller, more understandable ones.
• Removing duplicate code.
• Optimizing project and module structure.
• Adding or improving tests to ensure safety of changes.

An example of simple refactoring of a function in Python:

# Was

def calc_area(w, h):
    return w * h

# Now

def calculate_rectangle_area(width, height):
    return width * height

This approach improves code maintenance and development.
