About this gig
Need a Vapi voice AI agent that handles real calls? I build production voice agents on Vapi (also Twilio and LiveKit) inbound and outbound calls with low-latency speech-to-text, LLM reasoning (OpenAI, Claude, Grok), and natural text-to-speech. Ideal for AI receptionists, appointment booking, lead qualification, and sales or support calls.
What you get:
- A working Vapi voice agent inbound/outbound calling, live and deployed
- Custom call flows, IVR, barge-in (interruption handling), human handoff, fallback logic
- Function calling + integrations: calendar, CRM, database, your own APIs
- Natural voices (ElevenLabs / Vapi voices) tuned to your use case
- Clean, documented setup you own Twilio or LiveKit instead of Vapi if you prefer
Why me: 5.0 rating, voice AI engineer, 1-hour average reply, 100% on-time delivery.
New to Vapi? Message me and I'll scope your call flow, then send a quick demo plan or custom quote. Let's ship an agent that answers, books, and follows up.

I build production-grade Voice AI agents using LiveKit, Twilio, and Python. I’ve implemented real-time inbound/outbound call flows with low-latency streaming, clean turn-taking, and barge-in handling. I improve reliability by tuning VAD, handling jitter/packet loss, and adding retries plus consistent call-state. I containerize and deploy voice agents on AWS so they run stable in production with logging and monitoring.

FAQ
Can the voice agent support barge-in (caller interruption)?
Yes, I can implement barge-in so the caller can interrupt the AI agent mid-speech using our voice API features.
Will calls be recorded or saved?
By default, only minimal logging is used. Full call recording or transcripts can be added if needed.
Can the bot transfer calls to a human agent?
Yes, we can include a handoff to a human by detecting keywords, prompts, or using a dashboard trigger.
Which languages can the agent understand and speak?
I default to English, but I can add other languages with the right STT/TTS models. Let me know which ones you need.
Do you offer support after delivery?
Yes, standard includes 7–15 days of free support for minor fixes. Extended or ongoing support can be added as a paid service.
Do you build on Vapi specifically?
Yes, Vapi is my default. I also build on Twilio and LiveKit if you prefer.
