A couple things that may be deterring clients. Your overview makes absolutely no sense at all. It says nothing about what you do and how you can help clients.
Secondly, you have your English set as Fluent and it's not. You're Basic at best. Clients can tell this from your overview and they see it as being dishonest.
You need to take some tests in your area of expertise and add a portfolio. It takes a lot of work to have a standout profile, and clients have no reason to look at yours. You are competing against thousands of freelancers, you have to stand out if you want to succeed here.
