About this gig
Advanced AI Voice Agents with n8n, Vapi & Retell AI
Manual calling is a thing of the past. I build high-performance AI Voice Agent ecosystems using n8n to bridge the gap between Vapi/Retell AI and your business tools. I specialize in ultra-low latency setups that sound human and act fast.
WHAT I BUILD FOR YOU:
- Inbound/Outbound Logic: Trigger Vapi/Retell calls from any CRM or lead form.
- Real-Time Tooling: Connect your AI Agent to "Live Tools" via n8n to check inventory or live data.
- Smart Booking: Real-time Google Calendar/Calendly scheduling during the call.
- Post-Call Mastery: Auto-sync transcripts, summaries, and sentiment to HubSpot, GoHighLevel, or Airtable.
- n8n Self-Hosting: Assistance setting up n8n on your own server for data privacy and 0 cost per execution.
- Custom API Hooks: Deep integration for any software with an API.
WHY CHOOSE THIS GIG?
- Latency Optimization: I build "Lean Workflows" in n8n so your AI doesn't have awkward pauses.
- Cost Efficiency: n8n allows for unlimited scaling without the heavy "per-op" costs of Make.
- Reliable Support: Full documentation and a support window included.

FAQ
1. Do I need to have my own API keys and accounts?
Yes. You'll need active accounts for Make.com and your chosen voice platform (Vapi, Retell, etc.). I'll guide you on sharing secure editor access — no main login credentials needed.
2. Which AI voice platform is best for me?
Vapi = best for customization. Retell = best for natural, low-latency conversations. Bland AI = best for high-volume outbound calls. Not sure? Message me and I'll recommend the right fit.
3. Can the AI book appointments during the call?
Yes. The agent checks your Google Calendar or Calendly in real-time, offers available slots, and books instantly. Automated SMS and email confirmations are sent the moment the call ends.
4. How do you reduce robotic pauses during calls?
I optimize Make.com scenarios using webhooks and lean logic paths so data loads in milliseconds. System prompts and server settings are fine-tuned to keep conversations natural and fluid.
5: Can I see call transcripts and summaries?
Yes. After every call, a full transcript, AI summary, and sentiment analysis are automatically pushed to your CRM or Google Sheet — giving you clear insight into every conversation.
