Hey !
My name is Andreas Johansson, I have a computer science degree here in Sweden. I've worked natively with Android over the past couple of months and I would say your project's needs are needs I could fulfill. I have both experience with front-end and back-end development.
How would I about working with your project?
From what I can gather from your description, you want an app that shows deals and coupons from major online shopping websites. To integrate this feature I would let the user scroll the app for deals and coupons. With progressive downloading regarding data through JSON from a repository. I would design a simple but useful UI, so each and everyone of your users can understand the app to the fullest.
Best regards,
Andreas Johansson
