About this gig

Turn your documents into an AI that actually answers questions correctly.


Most AI chatbots make things up. I build n8n + LangChain automations that 

train an AI on YOUR documents PDFs, Notion, Google Drive, your website 

so it answers accurately, with sources cited, every time.


WHAT I BUILD:

  • AI chatbot trained on your PDFs, docs, or knowledge base
  • Multi-source support: PDFs + Notion + Google Drive + website content
  • Source citations see exactly where each answer came from
  • Vector database setup (Pinecone, Qdrant, Supabase)
  • Deployed to WhatsApp, Telegram, Slack, or your website
  • Self-hosted option for data privacy


WHY ME :

  • Real experience building and debugging production RAG pipelines including fixing vector dimension mismatches and improving retrieval accuracy (not just connecting an API and calling it done).
  • I test every chatbot against real questions before delivery no surprises, no hallucinations.
  • Data engineering background: ETL pipelines, PostgreSQL, natural language querying.


TOOLS:

  • n8n,
  • LangChain
  • OpenAI
  • Claude
  • Pinecone
  • Qdrant
  • Supabase 
  • PostgreSQL


Message me your documents/use case I'll tell you exactly what's possible before you order.
