Hire the Best Interactive Voice Response Specialists
in Nigeria

Every business I've worked with that was losing leads had the same problem not a marketing problem, not a sales problem. A response problem. Calls going unanswered. Follow ups happening too late. Leads sitting in a CRM with nobody calling them back. That window closes fast. I build AI voice systems that close it automatically. I am an AI Voice Agent Developer specializing in Retell AI, Vapi, Twilio, GoHighLevel, n8n, and Make com. I design and deploy production-ready AI phone agents that answer calls 24/7, qualify leads through natural conversation, book appointments directly into your calendar, and trigger the right follow-up sequence the moment a call ends without any manual involvement from your team. I have built AI receptionists that went live handling real patient calls for medical clinics within days of kickoff. I have deployed outbound AI calling systems that dialled through hundreds of aged leads and reactivated deals the client had completely written off. I have engineered post-call automation workflows that eliminated manual CRM entry for sales teams handling over 300 calls per week. These are not demos. These are systems running inside real businesses right now. 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝 AI Voice Agents & Call Automation I build inbound AI receptionists and outbound AI calling systems using Retell AI, Vapi, and Twilio that handle real conversations, not scripted menus. The agent qualifies leads, books appointments, routes calls to the right person, and logs everything automatically. Systems include AI phone agents for inbound and outbound calls, AI receptionists for healthcare, real estate, legal, and home service businesses, AI lead qualification agents, appointment scheduling automation, IVR systems using Twilio Studio and TwiML, and post-call automation covering summaries, CRM updates, contact tagging, and follow up triggers. GoHighLevel CRM Automation I build complete GoHighLevel systems that capture, nurture, and convert leads without manual input. This covers pipeline setup and stage automation, missed call text back, multi step lead nurturing sequences, Twilio SMS workflows, appointment reminders, AI-powered lead qualification pipelines, and webhook integrations connecting GHL to your other tools. Your CRM should be a live, accurate picture of every lead not a storage dump nobody updates. Workflow Automation & System Integration Using n8n and Make com I build multi-step automation workflows that connect your tools and eliminate the manual work between them. Lead comes in, gets scored, CRM is updated, task is assigned, follow up is triggered all without a human touching anything. I have built 60+ node n8n workflows handling full lead-to-onboarding pipelines and Make com blueprints running automated client reporting across GA4, Google Ads, and Meta Ads delivered every Monday morning without anyone pressing a button.

In my most recent project, I built a low-latency AI voice receptionist for a local home services company, eliminating missed after-hours calls and automatically routing over 40 new booked jobs directly into GoHighLevel in the first month. I'm an AI voice agent developer. I hate calling a business and getting stuck with a clunky, robotic phone menu. I build low-latency, natural-sounding AI receptionists with Vapi and Retell AI. I help businesses fix their inbound call and outbound campaign bottlenecks. Most companies just want the phone answered and the leads put on their calendar. I set up Twilio Voice and ElevenLabs Turbo V2 so the AI sounds like a real person instead of a tin can. I connect these voice agents to GPT-4o or Claude so they can handle complex questions from your knowledge base. I spend a lot of time on latency tuning. A long awkward pause kills the conversation. I fix that. I don't just set up a basic prompt and call it a day. Real businesses have messy data. Callers mumble, mispronounce things, or give incomplete addresses. I build fuzzy matching and scoring algorithms in n8n so your system actually knows what the customer is talking about. I use webhooks and REST APIs to tie everything together behind the scenes. If a caller has an emergency, like a burst pipe or an urgent medical issue, I build a warm transfer to get them to a real person fast. You probably need your calls to do actual work. I use Make and n8n to push lead qualification data straight into CRMs like GoHighLevel, HubSpot, or Google Sheets. I also build out SMS follow-up and missed-call text-back sequences in GoHighLevel because customers expect text messages today. I handle the tricky stuff, like getting SMS consent mid-call without the agent accidentally reading the confirmation text out loud. After the call, I make sure the full call transcript, summary, and call outcome get logged directly into your CRM. I work heavily with home services, specifically plumbing and HVAC companies. Plumbers miss calls when they are stuck under a sink. I build AI dispatchers that check technician availability in real time and book the job. I also build these systems for real estate businesses that need help coordinating property access with subcontractors. And I work with healthcare clinics. They need calendar booking and patient intake that works perfectly. For my medical and legal clients, I make sure the AI states the required AI disclosures and call-recording consent right at the start of the call. If you want to run cold calling automation, I can set that up too. I build outbound campaigns that track lead pipeline stages, handle common objections, and follow up automatically. I'll even add duplicate number checking logic so you don't annoy your leads. I make sure the AI handles turn-taking and barge-in naturally, so it stops talking the second your customer interrupts. Send me a message with your current tech stack. Let's get your phone system sorted.

I help home service businesses, medical clinics, and agencies capture lost revenue by building 24/7 AI Voice Agents that answer calls, qualify leads, and book appointments directly into your calendar. Most businesses don’t have a lead problem, they have a response-time and follow-up problem. Every missed call after hours, slow callback, or manual scheduling back-and-forth reduces your conversion rate. I solve this by building human-sounding AI Receptionists that work inside your real business workflows, connecting cleanly to your CRM, forms, pipelines, and backend tools. I build systems designed for real business use, not fragile demo bots. What I Build & Automate 24/7 Inbound AI Receptionists: Natural-sounding agents that handle FAQs, route calls, and book appointments directly into GoHighLevel or Google Calendar. Outbound Speed-to-Lead Agents: Automated systems that call new web leads within 60 seconds to qualify them and secure the booking. Post-Call Automation: Automatic call logging, CRM tagging, call summaries, and triggered SMS follow-up sequences. Missed-Call Recovery: Instant text-back systems to capture leads when lines are busy. The Technical Stack I integrate specialized voice platforms with your existing infrastructure to ensure zero latency and flawless data syncing: Voice & AI Platforms: Vapi, Retell AI, Twilio, ElevenLabs, OpenAI/Claude API. CRM & Pipeline Management: GoHighLevel (GHL) Native Voice & API integrations, HubSpot. Workflow Automation: Make com, n8n, Zapier, Webhooks, custom API routing. The Process Scope: We map your specific call flow, objection handling, and business logic. Build: I engineer the conversational AI prompt to prevent hallucinations and keep the agent on script. Integrate: The agent is wired into your calendar and CRM to update live data in real-time. Refine: We test the workflow to ensure a natural, latency-free experience before launching. Let's Build Your System If you need a reliable, scalable Voice AI system that actually drives revenue, send me a message with: Your business type and target audience Your current CRM and booking software What you want automated (Inbound, Outbound, or both) I’ll review your setup and suggest the most practical, high-ROI approach for your business.
