Message

At VIRTUAL PROZ, I architect and deploy Generative AI, Agentic AI, and LLMOps solutions. I build Python and FastAPI services and retrieval pipelines using RAG, GraphRAG, and vector databases.

Previously, at VISA, I developed financial time-series anomaly detection models and an LLM reporting pipeline. At STEAMIST, I worked on a healthcare scheduling chatbot, medical data pipelines, and disease-prediction models; earlier, at ALPHA GAMES LAB, I developed Python ETL pipelines and backend services.
