About this gig

Is your RAG chatbot hallucinating, retrieving the wrong chunks, missing exact IDs, or giving users answers you cannot trust?


I debug existing RAG systems by reproducing the failure and tracing it to the stage actually causing the problem retrieval, ranking, metadata, context construction, follow-up rewriting, grounding, citations or answer behavior.


Depending on your package, I can:

  • reproduce and diagnose your failing examples
  • inspect the available retrieval/context evidence
  • add lightweight diagnostic visibility when required
  • fix the agreed RAG failure
  • rerun the same examples after the change
  • document remaining issues and rollback steps


I do not assume every RAG problem is a prompt problem. If the available system data cannot prove the cause, I identify the missing evidence rather than guessing.


Python/FastAPI, Node.js/TypeScript, LangChain/custom RAG, Pinecone, PostgreSQL, pgvector, OpenAI and Gemini.

I build grounded AI assistants and RAG chatbots that turn PDFs, manuals, SOPs, policies, and internal knowledge into reliable answers with source citations. I focus on retrieval quality, document ingestion, exact identifiers, insufficient-evidence handling, and clean web chat experiences. I’ve built SourceChat, a working multi-format document RAG app, plus a technical knowledge assistant using hybrid vector + full-text retrieval. My stack includes Node.js/NestJS, React, OpenAI, Gemini, PostgreSQL/pgvector, Pinecone, and LangChain.
