Experience

Software Engineer

CME Group, Chicago, IL
Jan 2023 - Present · 3 years 6 months

Designed and implemented a full-stack risk management application in Python and Flask, focusing on automating complex data-driven tasks such as hedge trade conversions and margin calculations.
Integrated advanced mathematical and statistical models, employing Generative AI techniques to simulate and predict financial scenarios, significantly enhancing predictive accuracy and risk assessment capabilities by 15%.
Devised advanced risk management strategies using straddle option techniques, applying complex mathematical concepts to real-world scenarios.
Led the migration of the application to Google Cloud, successfully deploying it on the App Engine.
Initiated the migration process to transition the application to a Java-based domain within the cloud, enhancing efficiency and reducing operational costs.
Achieved first place in a company-wide hackathon, securing a $1000 prize, developing a profitable trading algorithm that outperformed other submissions.
