Ember,
There are a lot of great things in your profile, but it still needs to be much more assertive.
To say so, there are millions (1.5 million writers as of 2019) of freelancers on Upwork and many of them sound much more professional than you. You sound like you're giving it the old college try.
Upwork clilents are spending money on strangers on the Internet, so they want as close as possible to guaranteed results. They need to know you won't quit halfway through a project. They need to know you will deliver.
Professionals don't bother with "Hello." They start with "I am an expert editor and proofreader who can deliver the goods. With ______________ years of experience and _____________ training, I know my craft frontwards and backwards. I will get you publication ready copy on time ..."
I often say, pretend you've been doing this for 10 years. That's how confident you need to sound.
For example, you have the word "expert" as the 14th word in your profile. In my sentence, "I am an expert __________" it's the fourth word. You have to put your profile on steroids. You have to ramp up.
You say you are well organized. But freelancers work alone and remotely, so who cares if you're organized? That doesn't help the client. It helps you. Clients want to know how you're going to help them, not how organized your desk is.
You say "I am able to write, proofread and edit ..." Can't you be a bit more assertive than that? I am able ... doesn't sound like a lot of conviction, if you know what I mean.
Writer to writer, don't say "and much more!" If something is important, spell it out. If it's not important, don't hint at something. That's just strong writing 101. Along with that, don't say "etc." That's the same thing. If there's more to be said, say so. If there isn't, let it go.
Also, don't say "due to my professionalism," instead list the work you've done. "I've worked on novels, academic papers, non-fiction, white papers and online content." That's the way to sound professional. Don't just claim things out of thin air.
Those are my thoughts. Follow through on those, you should have a much stronger profile.
Good luck.
