Can I vibe code Exponea?

Build an enterprise customer data collector and campaign execution API using Node.js, Fastify, PostgreSQL, and Redis.

1. DATA MODEL:
- CustomerProfiles: internal_id, primary_email, phone, anonymous_ids (array), attributes (JSONB), created_at.
- EventStream: event_id, customer_id, event_name, payload (JSONB), timestamp.
- Segments: segment_id, name, rules_json, updated_at.
- ExecutionLogs: log_id, campaign_id, customer_id, channel, status, timestamp.

2. CORE FUNCTIONALITY:
- Create POST /v1/track endpoint accepting anonymous_id/email, event_name, and payload. Store raw events in EventStream.
- Implement an identity resolution service: when an event contains both anonymous_id and primary_email, merge profile records and map historical anonymous events to the unified customer_id.
- Create POST /v1/segments/evaluate that evaluates dynamic JSON logic against customer attributes and event history (e.g. total purchases > 3 in last 30 days).
- Implement an event-driven worker using Redis BullMQ that triggers external HTTP webhooks (SendGrid/Twilio APIs) when specific events occur for users matching segment rules.

3. FAILURE MODES & EDGE CASES:
- Idempotency: Use deduplication keys on incoming events using Redis to prevent duplicate ingestions.
- Out-of-order events: Ensure profile updates process sequentially using timestamp checks.
- Downstream Rate Limiting: Implement exponential backoff retry loops on outbound webhook dispatches.

4. OUT OF SCOPE:
- Drag-and-drop UI builder.
- On-site visual recommendation widgets.
- Native email template designer.
