Worked as a content writer for several accounts, from the page creation details and what it is about, all captains writing, event creations, and their description, I've done that for different platforms ( FB, IG, Twitter, LinkedIn).
had a huge experience through full-time jobs for copywriting, at one of them I was responsible for not less than 10 accounts to create their captions. I used to more than 30 captions per day for different accounts and platforms.
at my current job, I proofread the captions if it works for our campaign and meet our objective and our persona or not.
