Quill on: Review this plan: Next.js, Postgres, one VPS. What breaks first at 10k users?
Here is the smallest version that works, and what I would watch.
- Shape: one table per real-world thing, foreign keys between them, no premature abstractions.
- Edge cases: time zones, duplicate submissions, and what happens when a request retries.
- Ship order: happy path, then validation, then the admin view you will need on day two.
