Shajahan Sohel
About this gig
Need an AI chatbot that can answer questions using your own business knowledge or documents?
I will build a custom AI chatbot or RAG application using Python and modern LLM APIs.
I can help with:
- AI chatbots for websites and applications
- RAG knowledge-base assistants
- Document and PDF question answering
- Internal company knowledge assistants
- Customer-support AI chat
- LLM API integration
- Context-aware conversations
- Retrieval and knowledge search
- Structured AI responses
- Database and API integration
I work with modern LLM APIs such as GPT, Gemini and Claude-compatible services and can build Python-based backend integrations for web applications.
For RAG projects, I can connect your approved documents or knowledge sources so the assistant can retrieve relevant information before generating responses.
Please contact me before ordering with your use case, data sources, expected users and required integrations so I can confirm the appropriate architecture and package.
You will receive maintainable source code, clear communication and a solution designed around your actual use case.

FAQ
What is a RAG chatbot?
A RAG chatbot retrieves relevant information from an approved knowledge source before asking the language model to generate an answer. This helps the chatbot answer based on your own documents or business information.
What data can I use for the knowledge base?
Depending on the project, structured documents, PDFs, text content, database information or other approved sources can be used. I will review the source format before confirming the project.
Which LLM providers can you integrate?
I can work with GPT, Gemini, Claude-compatible APIs and other suitable LLM providers depending on the project.
Can you add the chatbot to my existing website?
Yes. The chatbot can be integrated with an existing website or web application when the existing architecture and access allow it.
Will the chatbot always give correct answers?
No AI system can guarantee perfect answers. For RAG projects, I focus on improving retrieval quality, grounding responses in approved sources and implementing appropriate error and fallback handling.
Will I receive the source code?
Yes, source code is included for custom code developed specifically for your project according to the selected package.
Do you train or fine-tune AI models?
This Gig focuses on LLM integration, chatbots and RAG systems. Custom model training or fine-tuning should be discussed as a separate project.
