[View Repository] |

Key Technical Implementations:

  • HPC Monte Carlo Engine (C++17): Developed a custom simulation module integrated via Pybind11. Utilizing OpenMP for full CPU core parallelization and SIMD Optimization, achieving 400x+ speedup over standard Python loops for 50,000+ path Geometric Brownian Motion (GBM) simulations.
  • Hybrid Volatility Forecasting: Implemented a unique pipeline where GARCH(1,1) econometric models are corrected by LSTM Neural Networks (PyTorch) to capture non-linear market anomalies and volatility clustering.
  • Dynamic Correlation (EWMA): Real-time covariance matrix updates to detect "correlation breakdown" during market stress events.
  • Statistical Backtesting: Automated validation layer using Kupiec (POF) and Christoffersen independence tests to ensure VaR model integrity.
  • Optimized Data Layer: Custom SQL caching layer and memory-aligned data structures to minimize cache misses and reduce data retrieval latency by 95%.
