Mubeen,
Don't take this the wrong way, but why would you define yourself as a good leader given the point that freelancers work for themselves? Who do you expect to lead?
Clients care about the service they are buying. That's what they are spending their money on.
A client doesn't necessarily care what software you use; they probably only care if what you do fits the operating system they have. So instead of saying "I know these software applications," what you should say is "I will make sure to use software that is compatible with your operating system."
The overall point is that the profile should be a sales pitch about your service or services and talk to clients on their level. What are you selling and how will your customers benefit from buying that from you?
Make sure you sound friendly and confident. But focus mostly on the service(s) and how clients will benefit. The rest will fall into place.
