About

Professional summary

I am a quantitative trader with a strong foundation in financial mathematics, applied statistics, and systematic options strategies. I use quantitative analysis to assess volatility, liquidity, skew, expiration risk, and trade opportunities.

I have experience trading defined-risk options strategies under proprietary firm capital. My work includes developing Python-based trading algorithms, monitoring hedges, evaluating performance across market regimes, and strengthening risk management practices.

I hold a Master of Science in Financial Mathematics from Johns Hopkins University and a Bachelor of Arts in Mathematical Economic Analysis from Rice University. My academic background includes probability theory, time series analysis, option pricing, stochastic differential equations, optimization, econometrics, and Monte Carlo methods.

I am proficient in Python, R, MATLAB, SQL, Excel, and LaTeX. I combine programming and statistical modeling skills to build analytical workflows, evaluate strategies, and solve financial and mathematical problems.

I also have experience supporting AI model development as a mathematics intelligence analyst and STEM subject matter expert. I design mathematical problems, create scoring rubrics, evaluate AI-generated solutions, and review reasoning for accuracy and logical consistency.
