About

MS in Data Science from NJIT. 5.5 years at Credit Suisse where I wore many hats - from catching billion-dollar bugs to leading teams across India and Switzerland.

My work spans industries: prevented $3 billion in losses at Credit Suisse, built criminal justice tech that diverted 1000+ people from incarceration, created AR systems tracking golf balls at 150+ mph, and most recently saved 72 person-hours daily through automation at PureHD.

I thrive on complex challenges that require deep technical knowledge and business understanding. Whether it's building real-time data pipelines, creating full-stack applications, or implementing ML models, I focus on measurable impact.
