My portfolio website is hosted on netlify and is linked to its respective github repo. Any push to master will automatically deploy the changes. Now, I wish to change the layout of my portfolio to match a template I found, however I've already started applying to jobs so I don't want to affect the existing portfolio until I'm done reworking it.

Now you may be saying branch > make changes > merge.

Right, my problem with that is, I want to push daily for github contribution tracker. It would take me several days to finish all the changes I wish to make and I don't want to break my streak. Thank you in advance.
