About me

Solving problems
that matter.

CS & Data Analytics undergraduate at IIT Patna (CPI 8.7) building systems at the intersection of software engineering, machine learning, and data analysis. I design tools that turn complex data into clear, actionable insight.

Recently shipped a Dollar Hegemony analysis system (XGBoost + LSTM + Transformer), a full-stack India Crime Analytics platform, and an AI fitness tracker — FitoGlobe. Always building something. Outside of tech, I follow cricket, dig into financial data, and keep a close eye on global markets.
