The About section of your profile is where you will introduce yourself to potential employers and offer some details about your experience and areas of interest.
You can write about yourself in the first-person or in the third-person in the About section. Just remember to keep it consistent throughout.
It's helpful to specify your availability for hire as well as any types of content you're particularly interested in writing. You can add images and videos to the About section as well. Make it your own!
Remember, your bio is essentially a sales pitch. Introduce yourself and your skills, but the focus should be on how you can put those skills to work for your client.
