DocPilot AI
End-to-end intelligent document processing with RAG & automation
Problem
Organizations struggle with manual document processing - extracting data from PDFs (invoices, BOQs, contracts), answering questions about documents, and triggering downstream workflows.
Approach
Built a full-stack RAG platform with semantic chunking (800 tokens with 120-token overlap), FAISS vector storage, and Groq-powered LLM inference. Implemented retrieval tuning (top-k, MMR) and similarity search optimization for accurate document Q&A with grounded generation. Built LLM evaluation framework with confidence scoring and source attribution checks. Integrated n8n for DocOps automation.
Outcome
Production-ready document intelligence platform with RAG Q&A, structured JSON extraction, LLM evaluation, and enterprise workflow automation. Deployed on Vercel + Render.
