A collection of projects I have built while exploring AI, backend systems, LLM workflows, RAG, and practical software products.

A document-based AI chatbot that uploads files, finds relevant text chunks, and answers questions using retrieval-augmented generation.

A multi-user chat application that analyzes the sentiment of each message and keeps conversation history in a database.

A personal AI assistant prototype with memory, user-aware chat, and a FastAPI backend designed for future RAG expansion.
