About this gig

**PLEASE CONTACT US BEFORE PLACING ORDER**


Are you looking for a smart AI chatbot that actually knows your business and gives real, useful answers?


I build custom AI chatbots powered by large language models like Claude and GPT-4. Whether you need a support bot, a sales assistant, or an internal knowledge tool, I can build it right.


What I work with:

  • RAG (Retrieval-Augmented Generation) to connect your chatbot to your own docs, PDFs, websites, or databases
  • Prompt engineering to shape how the bot speaks, what it knows, and how it handles edge cases
  • Tool use and function calling so your bot can search the web, pull live data, or call APIs
  • Memory and conversation history for more natural, context-aware chats
  • Custom system prompts and personas that match your brand voice


I can integrate:

  • Websites (React, Next.js, HTML)
  • WhatsApp, Telegram, Slack, and other platforms
  • Notion, Google Docs, PDFs as knowledge sources
  • REST APIs and third-party tools


I focus on clean, well-structured code and bots that actually work in production. I do not just hand you a wrapped ChatGPT widget. I build real pipelines with proper context management, vector search, and fallback handling.
