React Native Coder w/MySQL db management and updates

Please do not think I am an idiot...this project is easy...it is pretty much done ...so no bids over $500 please. NO TEAMS! ONLY A SINGLE DEVELOPER! The project has already been written in JavaScript, but has many bugs due to it requiring the use of Node.js as a webserver to initiate SSH connections and I decided to convert to react native. The project is called the merchant app which has been completely done (in JavaScript) but is currently in the process of having the way in which it connects to its back-end redone from SSH to websockets. There are two secured connections (currently) to the "married" back end that this app works with in a "Duo" setup that allows it to execute commands on the back end CLI. I have created a websocket connection on the back end to replace the current SSH connection & SSL secured connection that we call Thor that you will see in the source code of the already completed app. This first app contains nine screens. Many of the calls that are written to go through SSH or through Thor connection will simply be redone to operate directly on the new websocket connection which allows the app unfettered back-end CLI access to execute calls needed for the app. You will be provided a complete readme for the websocket and how to connect to it including all error codes that could occur upon connection. We also have a complete layout of how the web socket secures the infrastructure in that readme. It is approximately 9 or 10 pages and I have the source code available for you to (build & examine) in JavaScript to get an idea of how the app operates. When you choose to take the project you will be provided screen by screen direct calls and their post responses so that development can go quickly and smoothly. There are changes that will be made to this app as the connection setup is going to change so there will be a new start screen instead of the one you see when you build the source I provide you. Each screen that contains programming changes will be documented for rapid development. Each screen will have all appropriate calls and links already noted for development. The current source also utilizes code which controls a bluetooth receipt printer which has already been integrated and setup in the source. I want to be clear, the app you code will connect to a dedicated back-end server but will also access our website MySQL server, which too will need changes but is 98% complete. We have sample dedi server setup for testing and updating to the new apps specs. If the chosen developer agrees to continue, there will be 2 additional projects in the pipeline and this developer will get first bid. Both projects have some pre-existing source which can be built and is functional for visual demonstration. Key features will be added with these apps: Push Notifications, 2fa (OTP code), 2fa Google Auth setup. If you choose to complete all 3 you will be expected to transfer our company db to our dedicated company server.
