About this gig

I design and build Retrieval-Augmented Generation (RAG) systems and AI chatbots powered by large language models like GPT, Claude, and open-source alternatives via LangChain.


What you get:

  • A chatbot that answers accurately from YOUR documents/data (not generic hallucinated answers)
  • - Vector database setup (Pinecone, Chroma, FAISS, or similar)
  • - Source citation so users can trust the answers
  • - Clean integration into a website or API endpoint

Background: CS graduate (IIIT-Delhi) who has built a fully local RAG pipeline with domain classification and entity/relation extraction, plus other AI/ML production systems. I focus on retrieval quality, not just wiring an API call to an LLM.


Message me with your use case and data sources before ordering so I can recommend the right package.
