Can I vibecode Customer.io?

Act as an expert full-stack developer and build a robust customer engagement and marketing automation platform inspired by the core features of Customer.io. Use modern, highly-scalable web technologies such as Next.js (App Router), TypeScript, Tailwind CSS for the frontend, and a robust backend using Node.js, Express, and PostgreSQL (via Prisma or Drizzle ORM).

The platform must serve as a central hub for orchestrating personalized, cross-channel customer journeys based on real-time data and behavior. Please implement the following core features:

1. **Omnichannel Messaging & Campaigns:** Create a system to orchestrate and send messages across multiple channels, starting with Email and SMS. The application should include a modern design studio/editor for crafting responsive emails and messages. Support for Liquid templating (or similar) is required to inject dynamic, highly personalized content (e.g., user names, recent purchases) into the messages.

2. **Visual Workflow Builder:** Develop an intuitive drag-and-drop workflow builder interface (using libraries like React Flow) to design complex, event-triggered automation journeys. Users should be able to define entry triggers (e.g., 'User Signed Up', 'Added to Cart'), add logical conditions (delays, if/else branches based on user attributes or actions), and specify actions (send email, send SMS, update profile).

3. **Advanced Segmentation Engine:** Implement a powerful real-time audience segmentation engine. Users must be able to create precise segments based on a combination of profile data, behavioral events, and custom attributes. For example, creating a segment of "Users who signed up in the last 30 days AND have not completed onboarding".

4. **Data Pipelines & CDP Functionality:** The app should act as a lightweight Customer Data Platform (CDP). It needs an API endpoint to ingest events and update user profiles in real-time. Allow the creation of custom objects and collections to store data independent of individual user profiles, which can be referenced in messaging campaigns.

5. **Architecture and Infrastructure:**
- Provide a robust authentication and authorization system.
- Store all sensitive credentials (like email provider API keys) in a `.env` file and provide a `.env.example`.
- Ensure high performance and responsiveness with a polished, modern UI (incorporating smooth animations and a clean design system).
- Implement accessible keyboard navigation and clear validation/loading states.
- Include a comprehensive README explaining the architecture, setup instructions, database schema, and how to trigger events for testing.

6. **Testing and Reliability:** Include unit tests for the core segmentation and workflow logic. Add an end-to-end test verifying that a user can successfully create a segment, build a simple workflow, and trigger a simulated message. Ensure that all data models are strongly typed with TypeScript.

Do not include complex payment processing, built-in sender reputation management, or external AI features in this initial iteration. Focus strictly on building the core engine for ingestion, segmentation, and automated omnichannel orchestration.
