Build an App like Shaarli Bookmarking with multiple user login system in Node.js

Want an App like Shaarli in Node.js: [login to view URL] Features: - Make in Node.js - Use Browserify for browser JS. The browser JS bundle file should not go beyond 1MB. Please include the required projects carefully. - All features as in Shaarli. - Multiple user logins. - Database using pure JSON files OR NoSql, should be fast to handle a million users. Should be light on RAM. Please be careful when saving data to JSON files, it should not get corrupted over time OR whole purpose of this App will become useless. Better suggestions about database will be great. - Innovative GUI, will be good to use EZY for GUI (already bought): [login to view URL] - 2 simple plans: Free - Limited to 100 links/notes (entries). Paid - Unlimited. - Payment processors PayPal & Credit Card are ok for now. - Payments will be based on monthly subscriptions. - If a user does not make payment for 15 days, he will be notified before his account is made inactive automatically. There should be a feature in Admin Console to make the account active again. - User login should be PIN based which will be sent to his email. No password system needed. Please feel free to let me know of any questions. Please bid only if you can do it seriously. After this, I will also need mobile Apps for this in ReactJS, but that will be separate projects. ***Code that you send to me, will be a full copyright of my company. ***You should not be able to sell the code elsewhere to anyone else. Cheers!
