Lead AI Engineer at Startup | Risk Management ML Quant

I'm a physicist by training (Ph.D., University of Pennsylvania) who has spent about twenty years building models that financial institutions actually rely on. At Western Asset I built machine-learning models for fixed-income risk that held above 99% accuracy out of sample, and an NLP tool that cut a global compliance review from two weeks to under thirty minutes. Before that I engineered portfolio optimization and risk systems at Wilshire for institutions managing more than $1 trillion, and prototyped fraud detection at Microsoft. Today I build LLM and agent systems. If you work in finance and want to use AI well, I can help you pick the problems where it genuinely pays off, build something that holds up when compliance and real money are involved, and tell a real result from noise or overfitting. I also coach people moving into AI-in-finance roles. I've been through the current interview process at quant funds and AI labs myself, so I know what the bar looks like now.
