AI voice agents that answer calls and book appointments
Cover image for I designed and developed a
I designed and developed a specialized AI phone receptionist for veterinary clinics. The system handles real PSTN and SIP calls through FreeSWITCH. It combines streaming speech recognition, LLM orchestration and low-latency voice synthesis to communicate naturally with pet owners. The agent can answer questions about veterinary services, business hours, location, parking and clinic policies. It can identify the pet owner’s reason for calling, distinguish routine appointment requests from potentially urgent situations, check configured availability and guide the caller through a veterinary visit request. The system includes: • Real US telephone and SIP call handling • Pet-aware reason-for-visit collection • Routine, sick-visit and urgent-request routing • Veterinary service and provider information • Appointment booking, rescheduling and cancellation flows • Email confirmations and owner notifications • Safe escalation for urgent or unresolved situations • Call recordings, transcripts and structured summaries • Appointment status and administrative review • Configurable services, staff, schedules, policies and instructions • Replaceable speech recognition, LLM and voice providers I developed the telephony architecture, real-time conversational pipeline, backend APIs, veterinary call flows, appointment logic, email integration, administration, deployment and real-call testing. The agent does not diagnose animals or replace veterinary judgment. Urgent, uncertain or clinically sensitive requests are handled according to configured escalation rules. This is an independently developed product, not a paid client project.

Cover image for I designed and developed Anna
I designed and developed Anna Dental AI, a specialized phone receptionist for dental practices. The system answers real PSTN and SIP calls through FreeSWITCH and combines streaming speech recognition, LLM orchestration and low-latency voice synthesis to hold natural telephone conversations. Anna can answer questions about dental services, expected price ranges, business hours, providers and clinic policies. It can identify the requested treatment, match the caller with an appropriate provider, check configured availability and guide the caller through an appointment request. The system also includes: • Real US telephone and SIP call handling • Dental service and provider matching • Price, hours, location and policy questions • Appointment booking, rescheduling and cancellation flows • Email confirmations and appointment management links • Safe escalation for unresolved or sensitive requests • Call recordings, transcripts and structured summaries • Appointment status and administrative review • Configurable services, staff, schedules and agent instructions • Replaceable speech recognition, LLM and voice providers I developed the telephony architecture, real-time voice pipeline, backend APIs, appointment workflows, email integration, web administration, deployment and testing. The agent is designed for administrative communication and scheduling. It does not provide diagnoses or replace professional clinical judgment. This is an independently developed product, not a paid client project.

I designed and developed a specialized AI phone receptionist for hair and beauty salons. The system answers real telephone calls, explains salon services and prices, identifies the requested treatment, handles appointment requests and sends email confirmations. It uses FreeSWITCH and SIP telephony with streaming speech recognition, LLM orchestration and low-latency voice synthesis. The agent supports natural interruptions and is optimized for telephone-quality audio. I also built business-specific service matching and confirmation logic. During real-call testing, phrases such as “men’s haircut” produced several transcription variants, so the system uses aliases, conversational context and confirmation rules instead of relying on a single raw transcript. The management layer provides call recordings, transcripts, summaries, appointment status and configurable information such as services, staff, prices, opening hours, promotions and agent instructions. My responsibilities included telephony architecture, backend development, AI orchestration, appointment workflows, email integration, administration, deployment and real-call testing. This is an independently developed product, not a paid client project.

I designed and developed the operating layer behind a family of AI phone receptionists. The voice conversation is only the customer-facing surface. This platform gives business owners and administrators the tools required to understand, control and improve what happens during real telephone calls. The system supports multiple specialized workspaces, including dental practices, veterinary clinics, hair salons and beauty businesses. Each workspace has isolated services, staff, schedules, business information, appointment rules and agent instructions. Key capabilities include: • Centralized call and project overview • Call recordings and complete transcripts • Structured call summaries and extracted caller intent • Appointment status and outcome tracking • Service, staff and schedule administration • Business hours, pricing, promotions and knowledge management • Transfer and escalation configuration • Email confirmations and appointment management links • Voice, web, database and recording health monitoring • Web and React Native administration • Separate business workspaces on one shared architecture I developed the backend APIs, database models, administrative interfaces, authentication, email workflows, monitoring, deployment and integration with the real-time voice services. This project demonstrates that the system is more than an AI voice demo. It includes the operational controls, review workflow and verified action tracking required for real business use. This is an independently developed product, not a paid client project.

Build Ai Voice & Chat Agents | Business Process Automation
Cover image for Built an AI-powered web chat
Built an AI-powered web chat agent using Voiceflow to handle customer conversations and automate common website interactions. The agent understands visitor intent, retrieves relevant information from a business knowledge base using RAG, generates context-aware responses, and takes actions based on the conversation. It can handle FAQs, customer support, appointment scheduling, lead capture and qualification, customer information collection, issue reporting, and human handoff when needed. I also designed the workflow to connect with business systems such as CRMs, calendars, email, notifications, helpdesks, databases, and Google Sheets. The goal was to move beyond a simple chatbot and create a system that can understand conversations, access the right information, take useful actions, and keep business processes connected. This setup can be adapted to different business workflows, knowledge bases, conversation flows, and integrations.

Cover image for Built an AI voice agent
Built an AI voice agent to handle both inbound and outbound business calls. The agent can answer questions, qualify leads, collect caller information, book appointments, and transfer calls to a human when needed. I also connected the voice workflow with the CRM so important call and lead information can be passed to the right system automatically. The idea was to connect the conversation itself with the actions that happen after the call — from qualifying a lead to booking an appointment and keeping customer records updated. The workflow can be adapted based on the business, conversation flow, and integrations required.

Cover image for AI Web Chat Agent for
AI Web Chat Agent for Real Estate Lead Qualification & Appointment Booking Real estate websites attract buyers and sellers around the clock, but every conversation requires timely responses, the right questions, and accurate follow-up. As inquiry volume grows, manually managing these conversations becomes increasingly difficult, and valuable opportunities can be missed before an agent has a chance to respond. To address this, I built an AI-powered web chat agent that engages visitors the moment they arrive on the website. Rather than offering scripted replies, the assistant holds natural conversations, understands whether the visitor is looking to buy or sell, and adapts its questions based on the direction of the conversation. As the conversation progresses, the agent gathers important information such as property preferences, budget, preferred location, timeline, or selling requirements. It qualifies each inquiry in real time, allowing businesses to identify serious prospects without manually reviewing every conversation. The assistant is also connected to a knowledge base, enabling it to answer common questions about properties, services, and the buying or selling process while maintaining consistent and accurate responses. When a visitor is ready to move forward, the chatbot can schedule an appointment directly through the conversation, creating a smooth transition from the initial inquiry to the next step without requiring manual coordination. Every interaction is automatically recorded in Google Sheets and Airtable, ensuring customer details, qualification data, and conversation history remain organized and accessible for future follow-up. The chat experience includes interactive buttons alongside conversational AI, making it simple for visitors to navigate while still allowing natural, flexible conversations when additional guidance is needed.

Cover image for AI Voice Agent for Real
AI Voice Agent for Real Estate Lead Qualification & Appointment Booking Real estate businesses often lose qualified leads because every inquiry requires immediate attention, consistent follow-up, and manual qualification. This custom-built AI voice agent handles those initial conversations automatically, allowing sales teams to focus on serious buyers instead of repetitive administrative work. The agent begins each call with a time-aware greeting, such as Good Morning, Good Afternoon, or Good Evening, before engaging the caller in a natural, human-like conversation. During the conversation, the agent understands the caller's property requirements, asks relevant qualification questions, evaluates their level of interest, and captures the information needed for the sales team. When a caller demonstrates strong buying intent, the agent politely offers to schedule an appointment and books it automatically based on availability. If the caller is not yet ready to book, the conversation is still captured, and the customer's details, property requirements, and interest level are automatically recorded for future follow-up. All lead information is automatically stored in Airtable and Google Sheets, eliminating manual data entry and providing a structured record of every customer interaction. By handling the initial conversation automatically, the agent helps real estate businesses respond faster, spend less time on repetitive tasks, and focus on qualified leads that are ready to move forward.🚀

Cover image for Excited to announce that I've
Excited to announce that I've updated my #ElevenLabs Conversational AI Library for #FlutterFlow to support the official elevenlabs_agents #Flutter SDK. The old version was a custom WebSocket implementation that worked but had limitations. The new version is significantly better: - WebRTC instead of WebSocket - Ultra-low latency audio streaming. The difference is noticeable. - Proper turn-taking - Client-side VAD with intelligent interruption handling. No more awkward overlaps. - Secure architecture - API keys stay server-side where they belong and includes a #BuildShip template to get your back-end authentication going quickly. - Cleaner integration - Official SDK, secure App State variables, simpler initialization. https://marketplace.flutterflow.io/item/rwPaVMENBqTorJiznewx

Cover image for Most people think a shadow
Most people think a shadow is just a shadow. Study a real sundial: the shadow isn't a drop shadow or a perspective projection. It has personality. It's alive in a way digital shadows never are. time.connectio.com.au (http://time.connectio.com.au) uses real astronomical calculations to track the sun's position relative to you. Latitude, longitude, altitude. Shadow direction, length, softness, and colour temperature all shift exactly as they would in real life. The numerals have weight. The penumbra is properly soft. The whole piece breathes with the day/night cycle. Sunlight on your wall by day. Moonlight mode at night. Cast it to a 4K display and it becomes a meditative object in your home. I built this to explore beauty and truth in digital mediums. And partly because I'm a little unhinged when something captures my attention.

Cover image for If you build with FlutterFlow,
If you build with FlutterFlow, you know the pain: custom code has to follow a rigid structure, limited data types, and a pile of restrictions that trip up even experienced Dart developers, let alone AI models. I got sick of babysitting LLM output to make it FlutterFlow-compliant, so I built Custom Code Connect. What it does: • Describe any custom widget, action, function, or class in plain English • Highly trained AI workflow generates FlutterFlow-compatible Dart code • Automated compatibility review with a score and actionable fix notes • One-click deployment to your FlutterFlow project — no copy-paste, no manual fixes Custom Code Connect enforces FF's constraints at every step of the pipeline. 📺 Full tutorial: https://www.youtube.com/watch?v=aFTUqLSkAGY 🔗 Try it free: https://customcode.connectio.com.au/

Just shipped the most ridiculous thing i've built in a while. A focus timer that creates custom motivational songs about LITERALLY any goal you want to spend an hour on. Yes, really. AI has too much enthusiasm for mundane tasks and I'm here for it. Every 15 minutes you get a new banger. the results are slightly unhinged and always motivating. You'll find it at all good app retailers, especially Apple's App Store: https://testflight.apple.com/join/TB3PTdUu (https://testflight.apple.com/join/TB3PTdUu)and Google Play Store: https://play.google.com/store/apps/details?id=com.connectio.hourofpowe (https://play.google.com/store/apps/details?id=com.connectio.hourofpower)r

The AI Trick That Closed $10K While I Slept
Cover image for Boost Lead Conversion with 24/7 AI-Driven Instant Responses
Your leads are going cold while you sleep. The research is brutal: Respond to a lead within 5 minutes you're 100x more likely to reach them than if you wait 30 minutes. Wait until the next business day your conversion rate has already dropped by 90%. Most service businesses respond to leads in 4 to 24 hours. They call it "getting back to people." Prospects call it "I already booked someone else." This is a solvable problem. Not with more staff. Not with better time management. With a system that responds the moment a lead lands — regardless of what time it is, regardless of what day it is, regardless of whether your team is in a meeting or asleep. I build AI voice agents and automation pipelines that respond to new leads in under 60 seconds: → Instant SMS or email acknowledgment → AI agent follow-up call within minutes → Appointment booking before your competitor wakes up Speed to lead isn't a sales tactic anymore. It's table stakes. → Let me show you what this looks like for your business.
