You will get a multilingual Voice AI agent for calls, booking, and CRM automation
Top Rated
Project details
I will build a multilingual Voice AI agent that can handle inbound or outbound calls, answer business questions, qualify leads, book appointments, transfer calls, and update your CRM or workflow tools.
This is designed as a working business automation—not a scripted demo. I define the call flow, connect the voice and language models, integrate the required calendar or CRM, test realistic scenarios, and provide source code plus handover guidance.
Good fits include AI receptionists, appointment-booking agents, lead qualification, customer support, reminders, follow-ups, and internal call workflows. The implementation may use OpenAI, ElevenLabs or another voice provider, Twilio or compatible telephony, n8n, Node.js or Python, webhooks, and your existing business systems.
The Starter package covers one focused call flow and one primary integration. Please message me before ordering for high call volumes, regulated data, custom telephony infrastructure, or several complex integrations.

I’m Top Rated on Upwork with 26 completed jobs, 375 hours, $8K+ in earnings, and 25 client reviews. My focus is reliable real-world delivery—not just a demo. I test conversations, edge cases, integrations, handoffs, and deployment.
My process:
1. Understand your workflow and desired outcome
2. Define the simplest reliable architecture
3. Build and integrate the AI system
4. Test real-world scenarios and failure cases
5. Deploy, document, and hand over the solution
Tech stack: OpenAI API, Voice AI, RAG, n8n, Node.js, Python, FastAPI, React, Next.js, PostgreSQL, MongoDB, REST APIs, webhooks, Docker, AWS, and Vercel.
If you are losing leads through missed calls, slow follow-up, manual scheduling, or disconnected tools, send me your current workflow and desired result. I’ll help you turn it into a practical AI system that saves time and creates measurable business value.
