I am currently with Finicity (a part of MasterCard). Previously, I was with JP Morgan, New York as part of the model review group. Previously I was with SparkCognition, an AI start-up, as a Data Science Intern and was working on developing computer vision models for drone thermal imaging. Prior to that, I interned at WorldQuant, a hedge fund, where I built financial dashboards for the trading team and restructured their forex hedging algorithm to potentially save $1 Million per quarter.
