App for Credit Card Churners

Find app hosted here

This app collects data daily via web scrapers developed in R. The are then placed in a DynamoDB collection.

A list of all cards can be retrieved in JSON format at http://credit-cards.98he2uhpu4.us-east-2.elasticbeanstalk.com/CurrentCards/CurrentValue. The cards are ranked by their calculated dollar value. I used the conversion rates provided by thepointsguy.com monthly valuations.

The formula for Value is:

(Points) x (Rate) + Cash + StatementCredit + (150) x (Number of Free Nights) - AF x {0 if waived first year, 1 if not}

Points is the introductory points/miles rewards
The rate is what thepointsguy.com would pay for miles or points from a given reward program. For the ones he did not specify, I gave a rate of .01 per point.
Cash is the introductory cash rewards
Number of nights is how many nights are given as introductory bonus
I multiplied nights by 150 because that is typically what I would try and pay for a night.
If the fee is waived the first year, I didn't subtract it. If it is paid immediately, I subtracted it. I did not take into account that you might lose your points if you cancel before the second year. I based this off gaining your rewards and then closing your account before anniversary.

So for example Club Carlson:

I want to enhance the front-end by using async filters in angular. I am open to any other suggestions as well!
