About Me

Final-year B.Tech AI & Data Science student at CGC Landran โ€” building systems at the intersection of research and real engineering.

I specialize in LLM fine-tuning RAG pipelines and local AI deployment. My flagship project, ARIA, is a fully local Windows AI assistant with a 15-module architecture, STT, voice engine and Stable Diffusion integration
