That’s because my work is almost always under NDA. But I’ve got video testimonials and screenshots from real clients—just ask. 🎥🧾 👋 Who am I? I’ve spent the last 5 years designing and scaling chatbot systems that do more than just “chat.” I build flows that engage, qualify, and convert. My core platform is ManyChat, or ChatBotbuilder where I’ve been a certified expert since 2019. But I don’t stop at just building bots. I engineer full systems — connecting platforms like: 🔁 Make (Integromat) — my preferred automation tool (more flexible than Zapier) 📞 VAPI (VoiceBots) — for real-time phone conversations 💬 WhatsApp, Messenger, Instagram DMs, Telegram, SMS, Email 📆 Calendly, 📊 Google Sheets, 📈 Go High Level, 🧠 OpenAI, and more 🎯 What can I build for you? One example: A Facebook lead gets captured → Make sends the data to VAPI → A VoiceBot calls the lead → Asks qualifying questions → ChatGPT analyzes responses → CRM is updated → WhatsApp/Messenger follow-up is triggered With VAPI, I can: 🔓 Pass data into the VoiceBot: name, email, CRM ID, booking link, etc. 🎙️ Extract answers in real time as variables (e.g. “budget”, “timeline”, “needs”) 🤖 Analyze responses with ChatGPT to determine quality, tone, and urgency 📤 Push summaries or data into a table, Google Sheet, or Go High Level profile It’s powerful, flexible, and fully customizable. ⚙️ VAPI Latency Breakdown (Optimized for Real-Time Voice) ⏱️ Typical roundtrip: ~1000ms total 🗣️ Speech-to-Text (Transcriber): ~300ms 📍 Endpointing: ~100ms 💡 AI response generation (ChatGPT): ~400ms 🔊 Text-to-Speech (Voice): ~200ms ⚡ That’s fast enough to feel natural — even in a real conversation. 💻 Beyond Chatbots — Building with Lovable In addition to automations and voice systems, I also develop full-stack web applications using Lovable, where I’ve spent over 4,000 credits building and refining real-world projects. Lovable allows for “vibe coding” — fast, flexible development that bridges the gap between no-code and full code — and I know the platform deeply, including its database and deployment flows. I’ve built and deployed multiple projects through Lovable, including two fully functional web apps that I’m proud to demo: An AI-powered classified listings platform app.upworkmarketing.com A customizable AI chat widget and management platform If you’re looking for someone who can take your idea and turn it into a working app or SaaS platform quickly — while maintaining solid architecture — that’s exactly what I do. 🎓 My background 🎓 Bachelor’s in Economics 📐 Postgrad in Commercial Property Valuation 💼 POWER MBA Graduate ₿ Certified in Cryptocurrency (University of Nicosia) I’m a native English speaker with global clients — from Vancouver 🇨🇦 to Dubai 🇦🇪 — and I’ve built bots in: 🇮🇱 Hebrew 🇫🇷 French 🇪🇸 Spanish 🇬🇧🇺🇸 English 👇 Why work with me?
