Final year CSE student building real things at the intersection of web, cloud, and AI.

Chairperson of NSDC MEC. Final year CSE student at Model Engineering College. I care about systems that are fast, elegant, and genuinely useful — from a Flutter expense app used by real people to a production RAG pipeline built during my internship at Press Ganey.
