I'm looking for a developer highly proficient in ---------- who can build a platform that would include:
- An RSS reader (there is a plugin for this)
- An ability to add multiple RSS feeds, mark articles as read (very similar to inoreader or Feedly, except much simpler)
- An ability to sign up, log in, log out etc
- An ability to subscribe (likely using stripe)

Optionals but good:
- An app on the app stores
- Ability to refer friends and be rewarded with a discount for those referrals

I'm looking for work to start ASAP.
