I am a Data Science Leader driven by the intersection of rigorous Statistics and scalable Product Management. With 10+ years of experience, I specialize in transforming abstract business challenges into high-performing ML products that drive the bottom line.
My methodology is rooted in mathematical precision - utilizing Probabilities, Expected Variance, and Matrix operations to build models that don't just predict, but optimize. I believe in Optimal Coding practices: writing clean, high-performance logic that bridges the gap between a prototype and a production-grade AI solution.
