About this gig

Need an AI that can answer questions from your own documents with verifiable sources, not hallucinations?

I build production-grade RAG (Retrieval-Augmented Generation) systems used in regulated environments where accuracy and traceability matter. Every answer is tied back to the source document, so you can defend the output to clients, auditors, or regulators.

What you get:

  • Document ingestion pipeline (PDF, DOCX, HTML, CSV)
  • Vector store with ChromaDB and semantic + keyword hybrid search
  • FastAPI backend with streaming chat endpoints
  • Source citations linking back to original documents
  • Clean React chat interface (or integration with your existing app)
  • Provider abstraction run on local Ollama or cloud (OpenAI, Anthropic, Azure)

Best fit for:

  • Legal firms searching contracts and case law
  • Healthcare and compliance teams
  • Internal knowledge bases
  • Customer support over product docs
  • Research libraries

  • Programming language

    • Python

  • Expertise

    • Algorithms & Data structures
    • Databases
    • Source control
    • Testing procedures

  • Frontend framework

    • Angular
    • Flutter
    • jQuery
    • Nuxt.js
    • React.js

  • Backend framework

    • Django
    • Laravel
    • NestJS
    • Next.js
    • Node.js

  • AI & low/no code builders

    • Firebase Studio
    • FlutterFlow
    • Webflow
    • Wappler
    • Backendless
