About this gig
Stop Losing Customers to Missed Calls. Your Business Needs an AI That Never Sleeps.
Every unanswered call is a lost sale. Every after-hours inquiry that goes to voicemail is a customer going to your competitor.
I build AI Voice Agents that answer, qualify, book, and follow up 24/7, without a single human on the line. This isn't a chatbot. This is a fully conversational AI phone agent that sounds human.
Use Cases I specialize in:
- Real Estate: Inbound lead qualification & booking directly into GoHighLevel/Salesforce.
- Dental/Medical: HIPAA-aware appointment scheduling and reminders.
- E-commerce: "Where is my order?" support with database lookups.
- Cold Calling: Outbound sales agents with objection handling.
The Tech Stack:
- Voice Engine: Vapi AI / Bland AI / Twilio (optimized for <800ms latency).
- Brain: OpenAI (GPT-4o) or Groq (Llama 3) via LangChain.
- Orchestration: n8n Workflows for API connections (Calendar, CRM, Sheets).
Keywords:

FAQ
Does the AI sound robotic?
No. I use ultra-low latency voice providers like Vapi and ElevenLabs. It handles interruptions and pauses naturally, sounding 95% human.
Can it book appointments in my Google Calendar?
Yes. I use n8n to connect the call directly to your calendar APIs to check availability and book slots in real-time.
What happens if the AI doesn't know the answer?
I program "fallback logic." The AI will politely offer to take a message or transfer the call to a human line immediately.
Do I need to pay for the AI tools separately?
Yes. You will need your own accounts for Vapi/Twilio/OpenAI. I will help you set these up so you own your data.
Can I integrate the AI agent with my existing application?
Absolutely! I will design your AI agent to integrate seamlessly with your current application or platform, ensuring smooth operation and interaction.
What technologies do you use to build the AI agents?
I use advanced frameworks like LangChain, LangGraph, Crew AI, and AutoGen to develop powerful, responsive, and efficient AI agents.
What type of AI agent can you create?
I can create chatbots, virtual assistants, or any custom AI agent for various applications including e-commerce, customer service, and more.
