Can I vibe code Fueled?

Build a server-side event tracking and forwarding microservice in Node.js/TypeScript using Hono or Fastify, designed to replace Fueled for a Shopify store.

1. DATA INGESTION & WEBHOOKS
- Create an endpoint `POST /api/webhooks/shopify/orders-create` that verifies Shopify HMAC signatures.
- Create a client-side ingestion endpoint `POST /api/events/track` that accepts custom browser events (page_view, add_to_cart, initiate_checkout) containing client-generated `event_id`, `fbp`, `fbc`, IP address, and user-agent.

2. DATA NORMALIZATION & PII HASHING
- Implement a utility function to format and SHA-256 hash customer identity fields (email, phone, first_name, last_name, city, state, zip, country).
- Ensure strings are lowercased and stripped of leading/trailing whitespace before hashing, following Meta CAPI requirements.

3. AD PLATFORM INTEGRATIONS
- Construct a Meta Conversions API (v19.0) client that formats ingested order and frontend events into Meta `data` payloads. Send payloads via HTTP POST to `https://graph.facebook.com/v19.0/{pixel_id}/events`.
- Construct a GA4 Measurement Protocol client forwarding events using `api_secret` and `measurement_id`.

4. DEDUPLICATION & QUEUING
- Ensure every event passes a unique `event_id` and `event_name` to both frontend Meta Pixel and backend CAPI requests.
- Implement a simple Redis or SQS worker queue to handle retries for failed outbound API calls with exponential backoff.

5. FAILURE HANDLING & LOGGING
- Log failed payloads and error responses from Meta/Google to a structured log system (or Console/Datadog).
- Out of scope: User interface dashboard, automated schema generation, multi-tenant billing.
