As a professional writer/editor who has written hundreds of pages of web content, I may be just the talent you are looking for. What's more, I have written app copy, including push notifications.
Here are more of my qualifications:
--I am fast and efficient, as my rating shows.
--I have been writing and editing published content for 20 years.
--I am a native English speaker. I was born and educated in the US.
--I have a Master of Science in Marketing from a prestigious university.
--Here is my online portfolio link, though it is a work in progress: storytelleur.crevado.com.
I look forward to hearing from you. I am happy to send you some work samples.
