Wikipedia is not for writing about yourself 
Mohammad, welcome to Wikipedia, but it is not a place like Facebook or LinkedIn for people to write about themselves. It is a quite different sort of site, a project to build an encyclopedia, so it is selective about subjects for articles, and writing about oneself is strongly discouraged, for reasons explained at Wikipedia is not about YOU and Wikipedia:Autobiography. 

You can find out more about Wikipedia at the WP:Welcome page and the WP:Introduction; also, perhaps you should read Wikipedia:Guidance for younger editors.
