We are working on MCQ portal. The frontend is React, TypeScript, GraphQL, Material UI Backend is Firebase: Firestore (NoSQL database, which is a document store instead of an entity store) Functions (serverless backend i.e. Node.js) AppConfig (A/B testing and configuration), Data (entity store / asset data) Cloudinary (image CDN and transforms) Hosting (static files / CDN) data transfer layer(i.e.transport for communication with the backend, GraphQL gradually mix in some web sockets) Mobile App - React Native, APIs are the Node / Firebase Functions. Mobile web and phone app use the same exact back-end minus Hosting and some of the Functions.
