N8n/ ai workflow specialist

# AI Voice Automation Developer Needed (n8n + Voice AI + API Integrations) I am looking for an experienced AI automation developer to build a production-ready workflow using n8n and a Voice AI platform (Retell AI, Vapi, or another comparable solution). The project involves creating an automated workflow that: * Receives lead information through a webhook or API. * Initiates an outbound AI phone call immediately after a lead is received. * Conducts a natural, conversational dialogue using a custom prompt. * Collects specific information during the conversation and accurately extracts structured data. * Sends the collected information back to n8n through a webhook. * Stores the structured data in Google Sheets (with the ability to expand to CRMs later). * Sends email and/or SMS notifications containing a summary of the conversation. * Includes transcripts and AI-generated summaries. * Has strong error handling, logging, and retry mechanisms. * Is modular and easy to duplicate for additional clients in the future. ### Required Experience Please apply only if you have experience with most of the following: * n8n * Voice AI platforms (Retell AI, Vapi, Bland AI, or similar) * OpenAI API * REST APIs and webhooks * Google Sheets API * Gmail and/or Twilio integrations * Prompt engineering for conversational AI ### Deliverables * Fully functional n8n workflow * Voice AI agent configuration * Complete API integrations * Documentation explaining the workflow * Simple onboarding process for new clients * Loom (or similar) walkthrough explaining the system When applying, please include: 1. Similar AI automation or voice AI projects you've built. 2. Which Voice AI platform you recommend and why. 3. Your estimated timeline. 4. Your fixed-price estimate for completing the project. I'm looking for someone who has built similar systems before and can create a clean, scalable solution rather than an experimental prototype.
