Job ID: 33096685

Budget: $10 – $50 USD

React Native
The exercise consists in introducing changes in already existing application:
1. allowing to apply several filters on the existing array of products (at the moment, moving several switches at once causes that the empty array is returned, in turn, selecting only one returns the array filtered correctly) ,
2. connecting the application to the firebase database (ready database at the moment is written and attached to the application in JSON file, I need to transfer it to the database in real time)
Adding a function, which will read user id, and to it will assign all his favorite products, etc. (in the existing application it is possible to add products to favorites, but after restarting the list of favorite products resets to zero)
