Prompt

System architecture diagram for a mobile application platform supporting iOS and Android clients. Users authenticate with OAuth2/OIDC, and the app communicates with a backend via an API gateway. Core services include user profiles, content delivery, notifications, and offline sync. Data storage uses PostgreSQL for transactions, Redis for cache, and S3 for media. Add push notifications via APNs/FCM, analytics pipelines, and CI/CD for mobile releases. Include monitoring and crash reporting.
Highlights
  • Key flows · Login flow: the mobile app authenticates via OAuth2/OIDC, receives JWTs, and the API Gateway validates tokens before routing to profile services.
  • Module responsibilities · Mobile Clients / Auth & Session: Authenticate users; Issue JWTs; Enforce session rules
  • Layer details · Mobile Clients: Modules include iOS & Android Apps, Auth & Session, API Gateway.

Key flows

Show all (3)
  • Login flow: the mobile app authenticates via OAuth2/OIDC, receives JWTs, and the API Gateway validates tokens before routing to profile services.
  • Sync flow: clients write offline changes, Sync Service reconciles updates, and cached content is refreshed from Redis and S3.
  • Analytics flow: mobile events stream into the analytics pipeline, are transformed with dbt, and surface in BI dashboards.
