Project Overview: A lean, high-performance lead

Project Overview: A lean, high-performance lead capture pipeline designed for speed and data hygiene. This foundational tier handles intake, strict input validation, and single CRM contact creation while ensuring prospects receive immediate automated replies.

Architecture & Key Features:

Deterministic Idempotency Keys: Generates a stable hash from the prospect's email and phone number. If a webhook retries or a user double-submits a form, the system prevents silent duplicate record creation in the CRM.

Automated Data Sanitation: A JavaScript validation layer lowercases emails, strips whitespace, and standardizes local phone numbers into exact E.164 formats before writing to the database.

CRM Upsert Routing: Seamlessly pushes sanitized lead data into HubSpot (or Airtable) custom properties.

Speed-to-Lead Notifications: Automatically dispatches a personalized email confirmation to the lead and a plain-text alert to the internal sales team the moment the payload is validated.
