India dev : node.js API and htm5 single page app with 3 views

Front end Angular powered. Other JS can be jquery or other framework for UI. All API calls so can reuse same JSON based web service for native apps too. Design should have fields for native and web site. But now only back end web services and front end angular with basic clean design need built. Will have 2 single page - one for end user and 1 for backend admin. means admin has to change url to see admin login, on main page cannot see admin login. 1. sign up/ login using g, fb, twtr, linkedin, email (with captcha). If email need confirm link in email. If other - no form to fill just name and email, internally store oauth url, id etc in our db 2. once loggedin user can see x notes or make a new note. Make a note is a simple text area where i can write or paste something and save it 3. existing note can be copied using browser right click or copy button (i understand needs flash to work) 4. preferences : user can decide how many notes to show, up to a max set in back end. Example in back end i can set 10 but a user can have just latest 2 to e shown. if you read all this post 'i read it' in bid to prove you read the requirements. 5. back end : report on users (paging old style, with de-activate check box, if selected that user cannot login and in stead see s message "Account de acivated" Also can see IP address and client details of each message of each user 6. back end will have a 2 fixed user ids with a small hidden text file on server to set change password. password will be encrypted MD5 backend url will be [login to view URL]
