• As a Data Scientist/Business Analyst at Amazon India, I've spent the last few years honing my skills in Machine Learning. My focus has been on Risk, Audit, and Operations domains, where I've been able to make a real impact. One project I'm particularly proud of involved rebuilding the Negative Seller Balance model, which resulted in a 28% improvement in accuracy and caught four times the number of bad actors, saving the company $100 million per year. I've also been involved in building decision tree models and automating Python scripts to help run multiple projects simultaneously. Through these and other projects, I've gained valuable experience in data engineering, analytics, and optimization.
