AI Voice Agent Development (Vapi/Twilio)

$10/hr Starting at $100

I build AI Voice Agents that answer calls, qualify leads, and book appointments 24/7 — so your business never misses a call, even after hours.

Using Vapi, Twilio Voice, and OpenAI, I design conversational voice agents that sound natural, follow your specific call flow, and integrate directly with your CRM or calendar. This isn't a generic chatbot bolted onto a phone line — it's a purpose-built voice system trained on your business logic.

What I build:
- AI receptionists for inbound call handling and FAQs
- Outbound AI voice agents for follow-ups, reminders, and lead reactivation
- Lead qualification agents that capture caller details and route hot leads
- Appointment booking agents synced to Google Calendar, Calendly, or GoHighLevel
- Call routing and human handoff when a live agent is needed
- Post-call automation: transcripts, summaries, CRM updates, and SMS follow-ups
- Custom prompt engineering to keep the agent accurate and on-script (no hallucinated answers)

Platforms I work with: Vapi, Twilio Voice, OpenAI (including Realtime API), ElevenLabs, GoHighLevel, and webhook-based automation (Make.com, n8n, Zapier).

Every build includes clean, documented handoff so your team isn't dependent on me to maintain it. If you're losing leads to missed calls or slow response times, this is built to fix exactly that.

Tell me about your call volume and use case, and I'll scope the right setup for you.
