How they connect
- Customer → Product: uses
- Product → Sign-in: who is this?
- Product → Database: SQL
- Product → Subscriptions: checkout
- Subscriptions → Product: payment succeeded
- Product → Background jobs: later
- Background jobs → Email: send
- Product → Uploads: upload
- Product → Errors: exceptions
- Product → Product analytics: events
Notes and decisions
- Product: Pages and API in one deploy
- Database: Postgres, with row-level security
- No Kubernetes, no microservices: Nothing here needs its own scale yet. Split a part out when a number says so.
