Hi, I'm Ahmed.
I have read your description and found that you want to Oauth 1.0 Authentication and get accesstoken, I can feel is it Facebook token? I already made such.
Relevant Skills and Experience
I have 9+ years experience of C# programming. I have already made such projects for big websites and without browsers (If possible).

Is it really Facebook? or something else? I can do for any!
