    Achievements

    I built an application to backtest and optimize multi-legged option trading strategies using Chi-squared feature reduction, orthogonal combinatorics, polynomial regression, neural networks, and boosted random forests that leverages sliding window cross-validation to prevent overfitting.

    I've helped grow a company to $120M in revenue, and another to 2,000 employees.
