You don't need ways to improve resume. You need hands on experience.
Do EE related projects you can do by yourself.
It doesn't have to be anything glorious, or groundbreaking, or perfect, or even finished. Just that they have to be made by yourself. Upload a few photos of each project, write some explanations, document the projects, keep some activity logs with weekly progress for bigger projects. Show a few key stages, not just the final object like it will be a commercial.
Make a blog page or create an account on some makers platform, and upload your work. Choose a free platform, like wordpress.com, or instructable.com, or hackaday.com, or anything alike. If you already have projects posted in forums or other online places, link to them. If you tinkered before but never published, make some pics, add some description, and upload what you worked.
In most of the places, projects alone will weight more than diploma, will put you in front of other competitors, will give you experience, and will teach you a lot of things that can not be learned other than by doing them.
Good luck!
