I'm not sure I follow your question, to be honest. You are asking someone to tell you how to create a good profile? Do you mean how to articulate what you've done, or actually what to do? I think where you might be encountering some difficulty is that most people in this space are focused on the admissions process - namely, how to convey your skills in the context of applications and interviews, as well as how to pick the right programs and so forth. You might be looking for more of a career counselor, which probably exists at your university.
It's possible I am not properly understanding your query, but I'm not sure where to guide you at this point.
