Can I vibe code BayEngage?

Build a self-hosted email and SMS marketing automation system tailored for ecommerce webhooks using Next.js 14 (App Router), PostgreSQL (Prisma), Redis (BullMQ), AWS SES, and Twilio.

1. DATA MODEL
- Customers: id, email, phone, external_store_id, consent_email (boolean), consent_sms (boolean), total_spent, orders_count, created_at.
- Flow: id, name, trigger_type ('checkout_abandoned', 'customer_created', 'order_fulfilled'), is_active.
- FlowStep: id, flow_id, step_order, type ('delay', 'send_email', 'send_sms'), delay_minutes, template_subject, template_body.
- CampaignLog: id, customer_id, flow_id, step_id, status ('pending', 'sent', 'failed', 'bounced'), scheduled_at, executed_at.

2. WEBHOOK INGESTION & FLOW EXECUTION
- Create secure REST endpoints for incoming store webhooks: POST /api/webhooks/shopify/carts-update, POST /api/webhooks/shopify/orders-create.
- On receiving 'carts-update' with unrecovered cart, upsert Customer and queue a BullMQ delay job matching the active 'checkout_abandoned' flow.
- On receiving 'orders-create', immediately check and cancel any pending BullMQ delayed jobs for that customer's abandoned cart flow.
- Process background queue jobs: evaluating delay timers, checking unsubscribe status, rendering dynamic tags like {{first_name}} and {{checkout_url}}, then calling AWS SES SDK or Twilio API.

3. COMPLIANCE & UN SUBSCRIBE SYSTEM
- Every email body must automatically append a cryptographically signed unsubscribe link (GET /api/unsubscribe?token=...).
- Handle GET /api/unsubscribe to immediately update customer consent_email = false and cancel pending flow jobs.
- Provide an inbound webhook handler POST /api/webhooks/aws-ses to automatically mark hard bounces and complaints as suppressed.

4. USER INTERFACE
- Next.js dashboard displaying active subscribers, flow performance stats (sent, opened, clicked, bounced), and flow builder UI.
- Template editor supporting custom HTML or Markdown preview for both Email and SMS content.

5. FAILURE MODES & OUT OF SCOPE
- Retry transient SES/Twilio network errors 3 times with exponential backoff before marking failed.
- Do NOT build an embedded WYSIWYG HTML email drag-and-drop designer; use clean raw HTML/Markdown inputs with standard macro tags.
