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 Iโ€™ve worked with has the same problem, and itโ€™s not marketing and itโ€™s not sales. Itโ€™s 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. Thatโ€™s the problem I solve. Iโ€™m 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. Hereโ€™s 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 canโ€™t 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: โœ… 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 โœ… 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 โœ… Missed-Call Recovery: instant text-back so a missed call never turns into a lost lead โœ… Post-Call Automation: call logging, CRM tagging, and follow-up sequences triggered the moment a call ends through Automated Workflow design โœ… Multi-Agent Workflows: Reception Agent, Lead Qualification Agent, Appointment Booking Agent, and Follow-Up Agent working together inside one system โœ… 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 itโ€™s 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 isnโ€™t a nice-to-have anymore. Itโ€™s 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: โœ” Specialized in AI Voice Agents, AI Receptionists, and AI Agent Development across Retell AI, Vapi, and ElevenLabs โœ” Deep experience with GoHighLevel automation, workflows, and CRM integration โœ” Strong background in n8n, Make, and Zapier for end-to-end Automated Workflow builds โœ” Skilled in Prompt Engineering, Conversational AI, and Natural Language Processing for human-like agent behavior โœ” Focused on business outcomes, Lead Generation, and ROI, not just implementation Letโ€™s Talk: Click the โ€œInvite to Jobโ€ or send me a message with your business type, how calls are currently handled, and what CRM or booking tool youโ€™re using. Iโ€™ll reply with a clear, practical plan for what an AI Voice Agent, AI Chatbot, or Virtual Assistant could look like for your business.

Is your business being slowed down by manual processes, disconnected software, repetitive admin work, or systems that no longer support the way your team operates? Whether youโ€™re losing time updating spreadsheets, moving data between apps, chasing client information, or dealing with automations that keep breaking, those problems eventually cost more than just time. They affect productivity, visibility, and growth. I help growing startups, small and medium-sized businesses (SMBs), agencies, consultants, healthcare providers, fitness companies, real estate firms, and other service-based businesses build, improve, troubleshoot, and scale the systems they rely on every day. Some clients come to me with an idea and need a complete solution built from the ground up. Others already have Airtable bases, n8n workflows, Softr applications, AI agents, AI voice agents, or existing automation workflows that need to be redesigned, expanded, integrated with other platforms, optimized for better performance, or fixed because theyโ€™re no longer reliable. I donโ€™t start with software. I start by understanding how your business operates, where time is being lost, and what your team needs to work more effectively. From there, I design practical solutions that fit your workflow instead of forcing your workflow to fit the software. My expertise includes: (1) Airtable CRM, custom business systems, interfaces, automations, relational databases, and scalable data architecture (2) AI agents for business operations, internal workflows, customer support, and knowledge management (3) AI voice agents for appointment booking, lead qualification, inbound calls, customer support, and follow-up (4) AI chatbots for websites, WhatsApp, and customer service (5) n8n workflow automation and business process optimization (6) Softr client portals, internal tools, and web applications (7) API integrations, custom webhooks, and third-party system integrations (8) Client onboarding, lead management, CRM automation, and sales workflows (9) Reporting dashboards, operational databases, analytics, and business intelligence systems Whether Iโ€™m building a new solution or improving an existing one, my goal is always the same: create reliable systems that reduce manual work, improve operational visibility, and save your team hours every week. Every solution is thoroughly tested, documented, and built with long-term reliability and scalability in mind. Clients choose to work with me because I focus on solving business challenges, not just connecting apps. I communicate clearly, pay attention to the details, and build systems that continue delivering value long after the project is complete. If youโ€™re looking for a partner who understands both business operations and the technical side of AI, automation, and system design, Iโ€™d love to hear about your project.
