The problem we are facing is that when logged into our application the products take long to display. Our home page needs to feel and load exactly like our competitor app. 2) Search Bar result: When searching something, it does not pick everything. I want the search bar result to be able to pick everything that relate to an item being searched. Please play a little bit with the competitor app to see how the search bar works, We need it to work exactly the same. To work on search bar you will need to work on server to make it function. 3) Sign up Page: i want people to be able to sign up with their phone number as well. Just like Facebook. If you go on facebook in your mobile application, you will see how they give you 2 options to select to sign up with your phone> I want it to be very similar to facebook. both phone number and email. 4) If someone is posting something for sale in our system when type their phone number, either in the title and description. The app should remove it, the removal of phone numbers algorithm needs to catch most combinations (with (), -, _ ,& ) . We have a chat system we want all communication to be inside the app. 5) I want you to grab the bug list in google play store and see where our app is crashing and fix all these crashes. Our server is in Amazon web server. Add facebook pixel, add google analytics.
