n8n Developer Needed for Lead Routing & CRM Integration

We are looking for an experienced n8n developer to build an automated lead routing and qualification pipeline for our marketing agency. Right now, our team spends way too much time manually copying inbound web form submissions into our CRM, categorizing project scopes, and notifying our account reps. We want to streamline this entire process in n8n. Incoming leads should be ingested automatically, passed through an OpenAI node to evaluate prospect intent and assign a qualification score, and then pushed straight into our CRM fields. High-priority leads also need to trigger immediate Slack notifications so our sales team can respond rapidly without warm prospects cooling off. Scope of Work: 1.Webhook Ingestion & Data Validation: Set up an n8n workflow to catch incoming form submission webhooks, clean messy inputs, and validate key JSON payload fields. 2.AI Lead Scoring & Categorization: Integrate an OpenAI node inside n8n to analyze the prospect's project brief text, evaluate intent, and output a structured lead score. 3.CRM Synchronization: Use n8n API nodes to automatically create new contact records or update existing lead profiles in our CRM with the enriched data. 4.Conditional Slack Notifications: Build logic branching inside n8n to send instant Slack alert cards to our sales channel whenever a high-value lead is identified. 5.Error Guardrails & Fallbacks: Configure standard error-handling nodes to catch API timeouts or missing fields so no form submission is ever dropped or lost silently. Requirements: 1.Proven hands-on experience building production workflows in n8n. 2.Strong proficiency with webhooks, REST API nodes, and complex JSON data structures. 3.Practical experience structuring OpenAI nodes for consistent JSON output inside n8n. Ability to build reliable error-handling and provide clear in-node docu
