You will get Document Q&A Chatbot (RAG) | PDF/Docs | LangChain + Python
Top Rated

Project details
I will build a Document Q&A assistant so you can ask questions in plain English and get accurate answers grounded in your PDFs/docs.
It ingests your files, creates a searchable knowledge base, and returns answers with citations (page/section) so you can verify quickly.
You’ll get clean output formatting (bullets/table when needed), “not found” handling, and basic guardrails to reduce hallucinations.
Deliverables include the working pipeline, simple run instructions, and a short test report using your sample questions.

Job Success
Bahawalpur, Pakistan - 12:26 pm local time
Typical work I deliver:
RAG assistants for docs/knowledge bases (embeddings, vector DB, citations, metadata filtering)
AI agents that call tools (APIs, SQL/Postgres, webhooks) to complete multi-step workflows with guardrails + fallbacks
FastAPI backends for AI products (structured JSON responses, background jobs, clean integration)
Data extraction pipelines when needed (OCR + parsing + normalization)
How I build it (so it doesn’t break later):
Start with a small first milestone: one end-to-end flow on your real examples
Add measurable checks: retrieval quality, schema validation, safe SQL/tool execution, and “I don’t know” behavior when context is missing
Keep cost + latency practical: caching where it helps, prompt versioning, and predictable output schemas
Ship with maintainability: clean code, Dockerized setup, and a short runbook your team can operate
Stack I work with: Python, FastAPI, LangChain/LangGraph, OpenAI-compatible LLMs, SQL/PostgreSQL, Docker, and vector databases (FAISS/pgvector/Pinecone-style). I can also support ML/DL (PyTorch) and computer vision when the project needs it, but my day-to-day work is building LLM systems that integrate into real products.
If you share your brief + sample data, I’ll propose a practical first milestone, timeline, and what “done” looks like. I’m comfortable with self-hosted setups (privacy constraints), and can deploy on Docker/cloud as required. I also add basic monitoring hooks so failures surface early (logs, alerts, and simple dashboards). Open to a quick call to align on scope and success metrics.
