I have submitted more than 30 proposals including this month and previous month and have not received a single response for my proposal. I have completed jobs with clients and have received good feedback. Can anyone review my profile and point out the mistakes and tips. Thanks, in advance.
you don't have an overview at all, just a random list of "skills" and then copy pasted feedback.
You are competing with literally hundreds of thousands of other entry level freelancers. Unless you at least have a coherent, well written overview which tells clients how hiring you will benefit their business, you won't get hired much.
