Hi Menglee, welcome to the Community!
Bitbucket Cloud URLs can not be customized. If you'd like to show your repositories in your resume, you can add a link to your Bitbucket Cloud account (https://bitbucket.org/<username>/), that will lead them to your profile and they'll be able to see your public repositories.
Is there a specific URL you wanted them to see? How exactly would you like this to be?
Let us know!
