Pricefox

Pricefox was an investor-backed mobile app that allowed users to find products and compare prices at nearby retail locations.

Users could search for an individual product by scanning the barcode, or create a whole shopping list to compare the total price of an entire shopping trip at multiple retailers at the same time.

The product and price databases were built by collecting, deduplicating, and combining data from several sources including crowd sourcing, manual scanning, and crawling of online retail flyers.

I developed the Android app as well as the backend system which included the crowd sourcing, web crawling, and powered all of the features of the app.
