Custom AI Chatbot Development for WhatsApp and Web Platforms

This page covers custom AI chatbot engineering. I build smart, conversational chatbots powered by modern LLMs (OpenAI, Claude, Llama) that accurately answer customer questions, qualify prospective buyers, and resolve support requests 24/7 without making things up.

The Bottleneck

Traditional rule-based chatbots feel frustrating because they break the moment a customer phrases a question slightly differently. On the other hand, generic AI chatbots hallucinate inaccurate pricing or unapproved promises. Businesses need chatbots that understand natural human conversation while remaining strictly grounded in verified company facts.

The Solution Flow

I build a retrieval-augmented generation (RAG) system or structured prompt pipeline connected to your product catalogs, FAQs, pricing sheets, and policies. When a visitor messages on WhatsApp or your website, the AI identifies customer intent, retrieves exact business answers, and responds naturally in your company brand voice.
