You can use the following regex pattern to remove a dot before the @ symbol in an email address:

.(?=[^@]*@)

Here is how you can do this in Python:

import re

email = "john.doe@example.com"
cleaned_email = re.sub(r'.(?=[^@]*@)', '', email)

print(cleaned_email)

This code snippet will remove any occurrence of a dot before the @ symbol in the email address "john.doe@example.com" and print the cleaned email address without the dot.
