Build an open enterprise Customer Data Platform MVP using Node.js, Next.js, PostgreSQL, and BullMQ.

1. DATA MODEL & SCHEMA:
- Models: RawEvents (source, payload, matched_id), UnifiedCustomers (id, primary_email, primary_phone, first_name, last_name, addresses, created_at), CustomerIdentities (customer_id, identity_type, identity_value), Orders (id, customer_id, channel, total_price, line_items, order_date), Segments (id, name, rules_json, target_destinations).
- Support storing raw un-deduplicated payload JSON alongside parsed schema.

2. IDENTITY RESOLUTION ENGINE:
- Implement a deterministic identity matching service.
- When a new order or profile payload arrives from Shopify or POS webhooks:
  a. Check for exact match on email, normalized phone (E.164 format), or explicit external ID.
  b. If match found, link identity record to existing UnifiedCustomer and update aggregated stats.
  c. If multiple conflicting accounts match different attributes (e.g. Email matches Account A, Phone matches Account B), merge Account B into Account A, logging the match history.
  d. If no match, instantiate a new UnifiedCustomer.

3. ANALYTICS & SEGMENTATION:
- Build a background worker using dbt or raw SQL window functions to calculate:
  - Recency, Frequency, Monetary (RFM) metrics per profile.
  - Total LTV, Average Order Value (AOV), Churn Probability (simple rule-based threshold).
- Allow UI users to query segments via visual builder: e.g., 'LTV > $500 AND Orders > 3 AND Last Order < 60 days'.

4. REVERSE ETL / ACTIVATION:
- Implement worker queues using BullMQ to handle segment export payloads.
- Build outbound sync workers for Meta Conversions/Custom Audiences API and Klaviyo API.
- Implement strict exponential backoff, rate-limiting, and error logging per destination connection.

5. OUT OF SCOPE & EDGE CASES:
- Exclude probabilistic machine learning models; use strict rule-based logic.
- Handle failure recovery gracefully: bad payload JSON must route to a Dead Letter Queue without stalling processing.
