Flutter developer wanted

For our video management platform, we want to build an app with Flutter for both Android and IOS. The app should be as simple as possible. It has to allow users to: - use the camera to record video - give the videos names - view recorded videos - delete recorded videos - Connect their device with the account in our database by using our Elixir and Phoenix API. The user can just enter a 5 digit code which is generated on their account our platform. With a token, the device will be greenlisted to dump content in our database. This token system is already built on the server side. - Upload videos to the users account on our database by using our Elixir and Phoenix API With simple, we mean simple: the standard functionality of both Android and IOS for e.g. the camera and maybe even the video playback, can be used. We need to build this app very lean. Possibly, we will need a autocue functionality as well. Then we will have create a layer over the native camera app to read out a script to users. This is will probably be built in a later stadium. There are wireframes available but they have to be modified and optimized for maximum simplicity. It should not be ugly, but we can compromise on the UX.
