Knowledge Copilot
Developed a Full-Stack RAG (Retrieval-Augmented Generation) Platform for scalable AI-powered knowledge retrieval, featuring semantic chunking and real-time streaming.
The Challenge
Modern enterprises generate massive amounts of unstructured data, making it increasingly difficult for employees to find contextual, accurate, and relevant information quickly. Standard keyword search mechanisms fail to understand intent or complex queries.
The objective was to engineer a scalable AI-powered workflow that could ingest enterprise datasets, perform semantic vector searches, and utilize agentic tool-use to reason through complex analytics workflows, all while delivering real-time responses to the end user.
The Solution
I developed a robust Full-Stack RAG (Retrieval-Augmented Generation) platform using FastAPI for the backend and React/Vite for a highly responsive frontend architecture.
The core of the system relies on semantic chunking and vector retrieval pipelines that significantly improve contextual search accuracy. To ensure a seamless user experience, the backend optimizes asynchronous processing and uses real-time streaming to deliver AI responses with exceptionally low latency.
