About this gig

Struggling to make your data (PDFs, docs, website content) searchable 

and answerable by AI? I build production-ready RAG (Retrieval-Augmented 

Generation) chatbots that give accurate, source-grounded answers not 

hallucinations.


WHAT YOU GET:

  • Custom RAG pipeline built with LangChain and LangGraph
  • Vector database setup (Supabase + pgvector, or MongoDB Atlas)
  • Multi-tenant support for separate knowledge bases per client
  • FastAPI backend ready to connect to any frontend
  • Bangla/English bilingual support available on request


WHY WORK WITH ME:

I build AI/ML pipelines professionally at Sonali Life Insurance PLC, 

and previously built multi-tenant RAG systems at Infinoz. I also hold 

9 published research papers in AI/ML, so this is applied engineering 

experience, not guesswork.


TECH STACK:

LangChain, LangGraph, FastAPI, PostgreSQL/Supabase, pgvector, 

OpenAI/Gemini/Groq API


Message me before ordering if your use case is unique; happy to scope 

it out first so we're aligned before work begins.
