Project details

If your team is spending hours searching through
documents, PDFs, and internal files to find answers
— this system fixes that instantly.

I build RAG (Retrieval Augmented Generation) chatbots
that are trained on your own documents. Users ask
questions in plain English and get instant, accurate
answers with source references — in under 3 seconds.

What this project includes:

→ Document ingestion (PDF, CSV, Word, internal docs)
→ Chunking, embedding and vector database setup
→ OpenAI or local LLM integration (Ollama supported)
→ Chat interface or API endpoint
→ Source citations with every answer
→ Deployed on your server or cloud environment

Real result: A client used this system to search
10,000+ PDFs instantly — cutting document search
time by 90% and reducing support workload by 70%.

This is not a generic chatbot. It only answers from
your documents — no hallucinations, no made-up facts.

Stack: Python, FastAPI, OpenAI, PostgreSQL,
Docker, AWS

Ready to turn your documents into a knowledge system?
Send me a message and I will map out the build in 24 hours.

Frontend / Full-Stack Dev — Simple API Integration (Existing App) Muddassar is a hard work but he needs very clear instructions on that the client actually wants. For example, he will create the backend tech part and not integrate it.

Where gaps remain he ignores them and places the onus on the client to bridge them.
