You will get AI Voice Assistant & Chatbot Development | LLM ChatGPT OpenAI Gpt3
Top Rated
Project details
You will get a production ready voice assistant and chatbot that answers from your data, captures leads, and books meetings. I design clean workflows in n8n using ChatGPT and OpenAI with optional RAG through Supabase or Pinecone so replies stay accurate and grounded. Calendar booking runs through Cal dot com or GoHighLevel and every contact is created or updated in your CRM with tags, notes, and pipeline stages. Webhooks move data in real time and a Google Sheets log gives quick visibility for reporting. You also get clear prompts, routing and fallback rules, rate limit protection, and a short runbook with a Loom walkthrough. This service is built for agencies and small businesses that want reliable lead capture, appointment booking, and CRM integration without babysitting.

Retell AI Voice Agent Developer | GoHighLevel & n8n Automation Expert
We hired Obed Wisdom to develop a full Retell AI voice agent, and he exceeded expectations. He built a smooth, human-like call flow that captures caller info, syncs with Make.com, and triggers automations effortlessly. Obed communicates clearly, understands complex integrations, and delivers results that actually work. I’d definitely work with him again for future voice automation projects.

I build AI Voice Agents, AI Receptionists, AI Calling Systems, and Conversational AI workflows that handle inbound and outbound communication while integrating directly into business operations.
If your business is missing calls, responding slowly to leads, or struggling with manual follow ups, I design systems that capture, qualify, route, and engage customers automatically.
These are not simple demos or disconnected workflows. I build production-ready systems using Retell AI, Twilio, Vapi, OpenAI, and ai automation.
𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 (𝗥𝗘𝗔𝗟 𝗦𝗬𝗦𝗧𝗘𝗠𝗦 𝗡𝗢𝗧 𝗝𝗨𝗦𝗧 𝗗𝗘𝗠𝗢𝗦)
I specialize in building production ready AI voice and automation infrastructures that operate inside real business environments:
• AI Voice Agents that answer calls immediately, speak naturally, and guide conversations
• AI Receptionists for service businesses (booking, routing, FAQs, call handling)
• AI Lead Qualification Systems for real estate, agencies, and sales teams
• AI Appointment Scheduling Systems integrated with calendars and CRMs
• Intelligent IVR Systems using Twilio, Retell AI, and Vapi
• Outbound AI Calling Systems for follow-ups, reminders, and lead engagement
These systems don’t just respond they take action:
→ Capture structured data
→ Update CRM records
→ Trigger workflows
→ Send SMS/email during or after calls
→ Route leads based on logic
𝗔𝗨𝗧𝗢𝗠𝗔𝗧𝗜𝗢𝗡 & 𝗦𝗬𝗦𝗧𝗘𝗠 𝗜𝗡𝗧𝗘𝗚𝗥𝗔𝗧𝗜𝗢𝗡
Beyond voice, I build end to end automation ecosystems that eliminate manual work and keep your operations running without bottlenecks.
Using tools like Make (Integromat), n8n, and custom APIs, I design workflows that:
• Automatically assign and route leads
• Trigger follow-ups across SMS, email, and voice
• Sync data between multiple platforms in real time
• Handle webhook-based events and backend logic
• Manage pipeline stages and contact updates
• Send internal alerts and notifications
The goal is simple: zero delays, zero manual chasing, full visibility.
𝑪𝑹𝑴 𝑨𝑼𝑻𝑶𝑴𝑨𝑻𝑰𝑶𝑵 & 𝑳𝑬𝑨𝑫 𝑴𝑨𝑵𝑨𝑮𝑬𝑴𝑬𝑵𝑻
I implement smart CRM systems that ensure every lead is tracked, nurtured, and converted.
𝗧𝘆𝗽𝗶𝗰𝗮𝗹 𝘀𝗲𝘁𝘂𝗽𝘀 𝗶𝗻𝗰𝗹𝘂𝗱𝗲:
• GoHighLevel automation and pipeline setup
• Zoho CRM and HubSpot integrations
• Lead capture and enrichment workflows
• Automated nurturing sequences (SMS, email, voice)
• Appointment reminders and reactivation campaigns
• AI driven lead qualification logic

I build reliable, real world systems that actually work under pressure:
• Instant call pickup (no awkward delays)
• Clean, structured data handling
• Stable integrations across multiple platforms
• Logic-based automation (not just triggers)
• Scalable architecture for high call volumes
Every system is designed for performance, not just functionality.

If you’re looking for basic setups or the cheapest option, I may not be the right fit.
But if you want a properly built AI voice and automation system that integrates into your business and delivers real results, then we will work well together...

Send me a message with:
• How do you currently handle inbound calls or new leads?
• Where do you feel leads are dropping off?
I will break down exactly how to fix it and what your system should look like.
