This looks pretty interesting! If anyone is looking for a tool to build a full fledge Back Office I warmly recommend react-admin (https://github.com/marmelab/react-admin/). Been using it for a year now and we went from 0 back office to a feature full one in no time!
React Admin is awesome. Combine it with Hasura (automatic GraphQL on top of PostgreSQL) and you can build an entire back office admin suite (API endpoints and admin front end) in a matter of hours. You end up writing more SQL than react as react-admin is basically a CRUD form generator.
