Hello Dear,
Good Day!
I am a full stack developer with 12 years experience and very much comfortable in developing the Facebook web app as I have worked on similar nature project. kindly give me more details so I can share my development plan along with detailed proposal.
A Facebook web app where a user can give permissions to it. The app will then get information about the pages they like, the posts they like from a fan page, the usernames of their friends, the pages their friends like, the posts their friends like from a fan page.
Best Regards,
SH
