Upwork is very competitive and it requires a good profile and a good cover letter when applying for jobs. Unless you have a super niche area that you are clustering your services around, you really need to stand out of the crowd. I suggest you to read articles on how to write a good Upwork cover letters and also watch some Youtube videos on profile set ups. You should give it sometime.
Best of Luck
You are the only one who knows the (unique) skills you have. Even if you were told what the super-niche areas are, what is the point of that if you don't offer those services? You can't make up skills.
I would suggest you articulate better your profile description - I see only 3,5 rows of text, featuring a generic description, and if I were a client I would not be impressed by that. What can you actually do for your clients and what results have you achieved?
