Looking to hire a react native developer for various projects -- 2

Requirements for the job: React js node js react native ios and android build redux mongodb or firebase (mongodb preferably) Clear knowledge of MVC pattern and object oriented design Ability to create and test the react app with a million of users. (related libraries for testing) Be a javaScript expert deal with time difference and reviews. I am in process of making a simple dating app with my own rules of matching and profiles. I am NOT looking for codes from github I have all those klones already and none of them works for me. I want someone to write beautiful models and controllers. You have to have knowledge of IOS and Android in react native for future. We start by making the web version first. All testing will be done with something like "EXPO" to test for all devices. Due to limits in my budget and since this is a personal project, I will split the work into small pieces which bring payments and milestone to smaller portions. But the work is consistent. I am looking to work with the right developer long term. Please in your proposal refer to one sample work you did. I'd like to see flow of your code. If you have a react app on app store already Viola, if not please share some codes you made in react native just to show you understand the flow and logic of programming. I will respond back in one or two days after I receive all submissions. Thank you
