We are building a react native (iOS and Android) app that is functioning (with calls to database) but the front-end look and feel needs updating.
We are looking for react native coder who has experience in the following: Typescript; React native; Native base; react-navigation.
The design work has already been done. You will be working alongside another coder who has build the app so far and continue on the backend.
The app has approximately 30 screens that need updating.
