I work as a designer and currently have my resume in the same (styled) PDF file as my portfolio. It's clearly readable and scannable, so I'm not worried about that part. I don't upload my resume or portfolio on job sites, I apply through company forms or email.
I can't have most of my portfolio uploaded on a site like Behance due to publishing restrictions from previous jobs.
Is there any reason not to merge the two files? Or should I have 1 with just the resume and one with resume + portfolio?
