I build AI-powered applications and backend systems with a focus on Generative AI, Retrieval-Augmented Generation (RAG), LLM applications, and Python-based APIs.
My current work explores practical AI systems using technologies such as LangChain, LangGraph, ChromaDB, Ollama, FastAPI, and SQLAlchemy.
