Successfully developed and implemented a proprietary volatility surface calibration model using C++ and Python, which reduced pricing discrepancies for exotic derivatives by 18% across a $750 million portfolio. This was critical for maintaining accurate mark-to-market valuations during periods of elevated market turbulence, ensuring robust risk assessment and capital allocation. The model’s enhanced predictive accuracy directly supported more competitive trading strategies and improved profitability for high-stakes structured product trading.
At JPMorgan Chase & Co., I constructed an improved Monte Carlo simulation framework in C++ and Python for credit default swaps, leading to a 10% reduction in capital at risk reporting discrepancies over 18 months, crucial for regulatory compliance. Furthermore, I optimized a machine learning-driven asset allocation model using R and KDB+/Q, boosting risk-adjusted returns by 75 basis points for a $2 billion fixed income portfolio by identifying subtle market inefficiencies. My analysis of large-scale market data using SQL and Python also identified persistent arbitrage opportunities, increasing daily P&L by an average of $80K.
