Architect a scalable pipeline that combines real-time alpha vectors with RL-driven portfolio allocation and trade execution
Build and maintain walk-forward and event-driven backtesting frameworks with realistic transaction cost and slippage models
Implement multi-metric validation frameworks beyond Sharpe/Sortino, including max drawdown, Calmar, CVaR, and risk-concentration metrics
Collaborate with researchers and portfolio managers to translate quantitative research into production-grade trading systems
Optimize performance for GPU-accelerated training and efficient data pipelines (SQL, cloud, or hybrid)
