Can I vibe code Maropost?

Build a custom marketing automation engine in Node.js (TypeScript) with a React admin dashboard designed to replace Maropost's core email/SMS workflow capabilities using third-party delivery APIs (Resend and Twilio).

1. DATA MODEL & ARCHITECTURE:
- Setup a PostgreSQL database using Prisma ORM with models: Contact (id, email, phone, attributes JSONB, status), Segment (id, name, sql_query, criteria JSONB), Campaign (id, name, type, body, status, sent_at), Workflow (id, name, trigger_event, canvas_nodes JSONB, status), ExecutionState (id, workflow_id, contact_id, current_node_id, state JSONB, next_run_at).
- Integrate Redis with BullMQ to manage asynchronous job processing, queue delays, and message dispatching.

2. CORE FUNCTIONALITY:
- Create an Express/Fastify API that receives webhooks from Shopify/WooCommerce (e.g., checkout_started, order_created) and matches them against active Workflows.
- Implement a Workflow Engine using state machines: parse canvas_nodes containing trigger, delay (e.g., wait 2 hours), condition (e.g., total_spent > $100), and action (send_email via Resend API, send_sms via Twilio API).
- Build a dynamic segmentation parser that runs scheduled SQL queries to evaluate custom JSON rules against Contact attributes.
- Provide an API endpoint for handling unsubscribes and webhooks for soft/hard bounces, updating Contact status immediately to prevent re-sending.

3. FAILURE MODES & RESILIENCY:
- Rate Limiting: Implement exponential backoff for third-party API rate limits (Resend/Twilio).
- Idempotency: Deduplicate webhook arrivals using idempotency keys stored in Redis with a 24-hour TTL.
- Poison Pill Handling: Wrap node execution logic in try/catch blocks; move failing jobs to a dead-letter queue (DLQ) after 3 retries without blocking other executions.

4. OUT OF SCOPE:
- Custom SMTP MTA server management (rely strictly on third-party APIs like Resend/Twilio/AWS SES).
- Drag-and-drop HTML email editor (use simple Markdown/HTML raw text input with handlebars rendering).
