What's the minimum time it would take you to bring up an application on a custom domain with at least a user signup/signin/forgot password flow with email confirmations plus a simple CRUD form (like a TODO or similar)? Assuming you were starting from a clean cloud server instance with nothing installed except Linux, And what tech stack would you use to do that?
