About this gig
Need a smart AI chatbot that talks to your customers 24/7 and never misses a lead?
I build custom AI chatbots that understand natural language, answer questions instantly, and handle real conversations on your website, Telegram, WhatsApp, or inside your app.
What your chatbot can do:
- Answer customer questions automatically, around the clock
- Qualify and capture leads while you sleep
- Book appointments and collect information
- Pull answers from your own docs, FAQs, or database
- Hand off to a human when needed
What I work with:
- ChatGPT (GPT-4o) and Google Gemini
- LangChain, Flowise, and Vapi
- Telegram, WhatsApp, website widgets, and app integration
- Connections to your CRM, Google Sheets, or APIs
I've built bots for clients across the US, UK, and Europe delivered on time, with clear setup instructions so you actually know how to use what you get.
- Message me with what you need before ordering, and I'll tell you honestly if I'm the right fit.

FAQ
What is an AI voice agent?
An AI voice agent is a smart assistant that can talk to customers naturally over phone or chat. It can answer questions, book appointments, collect information, and handle support tasks — just like a real human agent.
Do I need technical knowledge to use it?
No — I handle the full setup for you. You’ll get a ready-to-use system with simple instructions and support for integration.
What tools or platforms do you use?
I use advanced frameworks like OpenAI GPT-4, LangChain, Flowise, Autogen, and voice APIs such as Twilio or Vonage for calling and speech.

Unfortunately I never got to see the final product. No proper explanation of how to implement my bot was ever given. So I'm left with a bot I have no idea how to use or Implemented.
