Need full stack developer to work on CI and react native

I have a mobile app that I need to be fixed over the weekend, the app is built using react native and the backend is built using codeignite (CI). The developer to be hired is supposed to know both platforms and fix issues on both in addition to uploading on apple and google play stores. The issues are: 1- Special characters are not being displayed properly 2- order on admin panel is not being always maintained on the app 3- there are some things that are stored in admin panel and being displayed at all in app 4- when updating items, sometimes they are stored in the wrong place in db Please only bid if you are willing to finish through the weekend and upload both iOS and android builds
