About this gig

Want your app to answer questions from your own data, without making things up?


That's what I build. I'm Saif, a full-stack developer with 5 years of experience in React, Next.js and Node. Most of my work now is adding RAG-based AI to real products.


You send me your data (PDFs, docs, website pages or your database). I turn it into an AI chatbot or smart search that lives inside your app and shows where every answer came from.


What you get:

- Full RAG pipeline: chunking, embeddings, vector search

- OpenAI, Claude or an open-source LLM

- pgvector, Supabase, Pinecone or another vector database

- Chat UI in React / Next.js, or a clean API you plug in yourself

- Source citations, so users can trust the answers

- Clean, documented code and a walkthrough video


Works with SaaS products, internal tools, customer support sites, and mobile apps through an API.


Not sure if your project fits? Message me before ordering. Tell me what data you have and what you want the AI to do, and I'll reply with an honest plan and the package that makes sense.
