Ionic (react) mobile app for drivers of a delivery management platform

With Dropon (www.dropon.io) we help companies dealing with frequent deliveries.

We have a planning platform that is connected to our mobile app for drivers.
This mobile app is currently a Native Android app that we want to rewrite in Ionic.

The mobile app is used by drivers so that they:
- can see all their trips
- see information on different stops they have
- navigate to the destination (external and/or internal navigation app)
- scan barcodes
- take pictures
- perform actions when offline
- in the background, send geolocation every x seconds to backend
- ...

To rewrite the mobile app we want to use:
- Ionic with React
- Graphql (Apollo) with optimistic response for offline handling (with localstorage)

Experience with Ionic, React and GraphQL is a must have!
