I want your help to build a shopify app that integrates with the twitter API. The idea is for someone to log into the store with their twitter I.D and they will have a score an average score generated from the last 30 days of twitter activity. If their score is high enough they can proceed to the checkout to buy certain items. if their score isn't high enough then they can't see the proceed to checkout buttons. Thats pretty much it, a full in depth spec with designs will be given to the chosen party. Could you please send me some of your previous work that you have completed with the shopify platform when applying for the gig.
