Losing leads to missed calls? I build 24/7 AI Voice Agents & AI Receptionists using Retell AI, Vapi, ElevenLabs & GoHighLevel that answer, qualify, and book appointments automatically.
Every business Iโve worked with has the same problem, and itโs not marketing and itโs not sales. Itโs response time. A call comes in after hours and nobody picks up. A new lead sits in a CRM for six hours before anyone reaches out. A booking takes three back-and-forth texts just to get confirmed. That gap is where revenue quietly disappears, and most business owners never even see it happening.
Thatโs the problem I solve. Iโm an AI Agent Development specialist and AI Voice Agent developer, and I build 24/7 AI Receptionists that answer every call, qualify every lead, and book appointments straight into your calendar, no matter what time it is or how busy your team gets. Every agent I build runs on Conversational AI and Prompt Engineering, so it understands context and responds naturally instead of following a rigid script.
Hereโs how it usually plays out for the businesses I work with; A home service company is missing calls every night because the office closes at 5pm, but customers call at 8. I build them an AI Voice Agent that picks up instantly, sounds like a real person, and gets the job booked before the caller even thinks about calling a competitor. A medical or dental clinic is losing new patients because reception canโt keep up with call volume, so I build an AI Receptionist that handles the FAQs, checks availability, and books the appointment directly into their calendar. A real estate or service business has leads coming in from ads, but nobody calls them back fast enough, so I set up an AI Voice Agent that reaches out within 60 seconds of a new lead coming in, qualifies them on the spot, and hands off only the ones worth a real conversation.
What I Build As An AI voice & Chatbot developer:
โ 24/7 Inbound AI Receptionists: answer FAQs, route calls, and book appointments directly into your calendar using Interactive Voice Response (IVR) flows that feel natural, not robotic
โ Speed-to-Lead Outbound Agents: reach new leads within 60 seconds so they book before a competitor calls, built for serious Lead Generation and Appointment Setting
โ Missed-Call Recovery: instant text-back so a missed call never turns into a lost lead
โ Post-Call Automation: call logging, CRM tagging, and follow-up sequences triggered the moment a call ends through Automated Workflow design
โ Multi-Agent Workflows: Reception Agent, Lead Qualification Agent, Appointment Booking Agent, and Follow-Up Agent working together inside one system
โ AI Chatbot & Conversational AI assistants: For businesses that also want a Virtual Assistant handling website, WhatsApp, or SMS conversations alongside their voice agent
I build all of this using no-code and low-code platforms, so you get a fast, reliable AI Voice Agent without the cost or delay of custom development. Every system is powered by OpenAI API and Natural Language Processing (NLP) under the hood, so conversations stay accurate and on-topic.
Platforms I Work With As An AI Voice Agent & Chatbot Developer:
Voice & AI: Retell AI, Vapi, ElevenLabs, Bland AI, Twilio
CRM & Calendar: GoHighLevel (HighLevel), HubSpot, Salesforce, Google Calendar
Automation: n8n, Make, Zapier, Webhooks, API Integration
Every AI Receptionist I build also handles what happens after the call - things like logging the conversation, tagging the lead in your Customer Relationship Management system, and triggering a follow-up text automatically. This is the part most people forget to automate, and itโs usually where the real money is.
Industries I Work With As An AI Voice Agent & Chatbot Developer:
Home service businesses, medical and dental clinics, real estate agencies, law firms, agencies, SaaS companies, and other appointment-driven businesses that depend on the phone to bring in revenue.
If your business is one of them, an AI Voice Agent isnโt a nice-to-have anymore. Itโs the difference between a lead that books and a lead that goes to whoever calls them back first.
Why Clients Work With Me As An AI Voice Agent & Chatbot Developer:
โ Specialized in AI Voice Agents, AI Receptionists, and AI Agent Development across Retell AI, Vapi, and ElevenLabs
โ Deep experience with GoHighLevel automation, workflows, and CRM integration
โ Strong background in n8n, Make, and Zapier for end-to-end Automated Workflow builds
โ Skilled in Prompt Engineering, Conversational AI, and Natural Language Processing for human-like agent behavior
โ Focused on business outcomes, Lead Generation, and ROI, not just implementation

HIPAA-aware AI voice agents for healthcare โ built on Synthflow, Retell AI and ElevenLabs. I turn missed calls into booked appointments with 24/7 reception, appointment booking and CRM automation that capture every inquiry and route it into your real systems.
I specialize in production voice agents (Synthflow, Retell AI, Voiceflow, ElevenLabs) wired into your real systems โ GoHighLevel, HubSpot, EHR / booking tools, Twilio telephony, plus AI chat & WhatsApp assistants (ManyChat, WATI) โ with OpenAI / GPT-4o driving the conversation and n8n / Make orchestrating the workflow end to end.
Healthcare is where I'm strongest. Recent work includes:

24/7 AI shift-coordination for UK NHS healthcare staffing
Bilingual (EN / ES) after-hours patient reception (Miami)
Inbound AI receptionists for dental & medical clinics
AI voice agent for medical consults (Synthflow + PracticeQ / EHR)
I design with compliance in mind: HIPAA-aware architecture, PHI minimization, audit logging, and clear medical-escalation rules โ the AI never diagnoses or gives medical advice; it routes to your staff.
Beyond healthcare, I deliver the same voice + integration stack for clinics, agencies, startups, and appointment-driven service businesses.
What I deliver:
AI voice & chat agents: inbound / outbound calls (Twilio, VoIP), WhatsApp & web chat, FAQ, triage, appointment booking
Lead qualification, enrichment & conversion bots
Knowledge-base & RAG assistants (document / data retrieval, multi-agent)
AI automation for business operations (n8n, Make, Zapier) + API / webhook integration

I built my first Voice AI agent 24 months ago. It worked perfectly in testing. Then a caller with a heavy accent asked a question while their dog barked in the background, and the whole thing collapsed.
That project taught me something most AI developers learn too late: the demo is 10% of the work. The other 90% is everything that can go wrong - bad audio, CRM timeouts, users who say "um" fourteen times, edge cases nobody warned you about.
Now I only build AI that handles the chaos.
๐ช๐ต๐ฎ๐ ๐'๐๐ฒ ๐ฏ๐๐ถ๐น๐
๐ฉ๐ฎ๐ฟ๐ฝ๐ฎ is a HIPAA-compliant healthcare voice agent for multi-clinic practices. It answers calls 24/7, classifies caller intent across six categories, routes to the right staff, and books appointments. 2000+ calls handled in six weeks at a 100% pickup rate. Built HIPAA-aware with no PHI in logs and EMR integration.
๐๐ฒ๐น๐ผ is a productized AI voice receptionist for dental practices, live 24/7 with paying customers across three subscription tiers. It answers every call, books and reschedules appointments, handles FAQs, and escalates to staff only when needed, capturing the after-hours patients clinics were losing to voicemail.
๐ฉ๐ฒ๐ฟ๐ฑ๐ฎ๐ฝ๐ is a multi-tenant voice AI platform for home-service businesses like landscaping, HVAC, and plumbing. Each branded agent answers calls 24/7, books and qualifies jobs, syncs to Google and Outlook calendars, logs everything in GoHighLevel, and fires invoices automatically once the owner approves a job.
๐ค๐ฎ๐น๐ถ๐ณ๐๐ takes 40+ real estate calls daily. Not test calls - actual leads, live conversations, 92% intent accuracy measured across thousands of interactions. Built on VAPI with ElevenLabs voice, GoHighLevel CRM sync, and Google Calendar booking. It qualifies buyers, handles objections, and hands off to human agents without dropping context.
๐ฃ๐ฎ๐ฝ๐๐ฟ๐๐ answers research questions across 15,000+ academic papers. Hierarchical chunking, hybrid search with pgvector, Cohere reranking, and cited answers. It says "I don't know" when retrieval confidence is low. Researchers trust it because it doesn't make things up.
๐๐ ๐๐ฟ๐ฎ๐ป๐ธ generates legal documents with jurisdiction-aware retrieval. 700+ documents created with proper citations pulled from the right statutes. React frontend, Python backend, pgvector for legal precedent matching.
๐ฆ๐๐ฎ๐๐ฆ๐พ๐๐ถ๐ฟ๐ฒ handles hotel reception calls - booking inquiries, room availability, guest requests. Retell for voice, n8n workflows for automation, webhook integrations with property management systems.

I take on Voice AI agents, RAG systems, and AI MVPs. I'm useful when you're past the "exploring AI" phase and need something deployed. Less useful if you're still figuring out whether AI makes sense - though I'm happy to tell you if it doesn't.
Most of my projects are $2Kโ25K and take 2โ6 weeks. I don't disappear mid-project, I document everything, and I build with handoff in mind so you're not dependent on me forever.
