Production client system
Reliable answers across more than 500,000 documents
A production knowledge system that helped authorized users find answers across a very large document collection and see the source behind each answer.
- Fact 1
- 500K+ documents
- Fact 2
- Sub-second answers
- Fact 3
- Access-controlled results
The problem
The client managed more than half a million documents. Finding the right information was slow, and different users needed different levels of access.
What I built
I designed a search and answer system that organized the collection, combined more than one search method, checked which documents each user could access, and returned answers with supporting sources.
The result
Users received source-backed answers in under a second. The system also measured answer relevance so retrieval quality could be improved over time.
Technical details
For technical reviewers, the delivery used the following tools and platforms. The business problem and result remain the primary scope.
- Python
- LangChain
- Pinecone
- OpenAI
