Vikash Agrawal

IIT Bombay alumnus and Harvard certified Data Scientist architecting robust data backed risk strategies and predictive ML models at massive scale. I have optimized algorithmic risk frameworks for a $80 billion monthly transaction portfolio at PayPal and built multimillion dollar risk product at AmEX. I specialize in advanced statistical analytics, forecasting, and precision strategies that neutralize fraud, minimize user friction, and drive growth. Beyond the algorithms I am a dedicated fitness enthusiast, powerlifting medallist and a competitive badminton player bringing the exact same relentless discipline to my technical work.
