About this gig

Need an AI chatbot that can answer questions using your own documents, knowledge base, or business data?

I build custom AI chatbots using OpenAI, RAG, LangChain, vector databases, and modern AI workflows.

Instead of relying only on the model's general knowledge, your chatbot can retrieve relevant information from your provided data and use it to generate more context-aware responses.

What I can build

  • AI customer support chatbots
  • Document / PDF question-answering bots
  • Internal company knowledge assistants
  • RAG chatbots for websites or applications
  • AI assistants connected to APIs
  • Knowledge-base chatbots
  • Custom OpenAI API integrations
  • AI workflows with LangGraph
  • Chatbots with conversation history and context

RAG chatbot features

Depending on your requirements, I can implement:

PDF, DOCX, CSV or other document ingestion

Text chunking and embeddings

Vector database / semantic search

Retrieval-Augmented Generation (RAG)

Conversation history and context

Source-aware responses

OpenAI or other LLM integration

REST API integration

Custom chatbot logic

Basic testing and error handling

Why work with me?

I focus on building practical AI systems rather than simple chatbot wrappers.
