Feb 2025 - Present • 1 yr 8 mos

Designed and built a full Retrieval-Augmented Generation (RAG) system — the Secure PDF RAG Assistant — enabling users to upload PDFs and get AI-powered, source-cited answers. Implemented the complete pipeline: PDF text extraction, chunking, embeddings, vector storage (ChromaDB), and LLM-based answer generation using the OpenAI API. Added Google OAuth login for secure multi-user access, per-user chat history, and an admin dashboard. Currently extending the project with FastAPI, Docker, and CI/CD to build production-grade MLOps skills.
