About this gig
Looking for a custom AI chatbot that actually understands your business instead of giving generic ChatGPT answers?
I build production-ready RAG (Retrieval-Augmented Generation) chatbots that pull real, source-backed answers from your own documents, website, or database no hallucinated responses.
What you get:
- Custom RAG chatbot trained on your data (PDFs, websites, FAQs, databases)
- LangChain-based retrieval pipeline with a vector database (Pinecone, FAISS, or Chroma)
- Integration with OpenAI, Claude, or open-source LLMs
- Full API integration into your website, app, or CRM
- Clean, documented source code no vendor lock-in
Why work with me:
- Data Science background I optimize for retrieval accuracy, not just a working demo
- Clear communication, realistic timelines
- Full documentation so you're never stuck maintaining a black box
How it works: message me your use case I confirm RAG is the right fit you send your data I build, test, and deliver with documentation.
Message me before ordering I'll tell you honestly if RAG fits your problem.

FAQ
Can you integrate this RAG chatbot into my existing platform?
Yes, As an AI Integration specialist, I can build backend API endpoints to connect your custom RAG chatbot to your existing website, web app, or internal business software.
Is this service suitable for university projects?
Absolutely. I specialize in building foundational RAG pipelines and chatbots for academic projects. You will receive organized, well-documented Python source code that is easy to study and present.
What is a RAG chatbot, and how is it different from a normal chatbot?
A normal chatbot answers from generic training data and often makes things up. A RAG chatbot first searches your own documents or database, then answers using those real facts giving accurate, business-specific responses instead of guesses.
What data sources can you train it on?
PDFs, Word docs, text files, website content, FAQs, spreadsheets, and structured databases. Send me whatever knowledge base you have, and I'll turn it into a searchable system the chatbot pulls answers from.
Do I need my own OpenAI/API key?
Yes, you'll need your own API key so usage costs and the account stay in your name. If you don't have one, I'll guide you through setting it up in a few minutes.
Will I receive the full source code?
Yes, full source code is included with clear documentation, so you're never locked into me for future changes, hosting, or edits.
