Making knowledge accessible through conversational AI
The challenge: Decades of valuable programming discussions buried in email archives, difficult to search effectively.
My innovation: A RAG-powered chatbot that transforms static archives into interactive knowledge discovery.
Technical achievements:
- LangGraph implementation with source citations for trustworthy responses
- Multi-turn conversational interface with multiple retrievals per turn for complex technical queries
- 10% accuracy improvement through hybrid dense+sparse retrieval
- Local models for improved privacy and cost reduction vs OpenAI
