I transform theoretical AI potential into reliable, high-impact business infrastructure. I believe an AI system's true value is realized only when it operates flawlessly at scale, serving real users and delivering measurable outcomes. I lead end-to-end AI/ML initiatives across predictive analytics, NLP, computer vision, and automation—building scalable data platforms, dashboards, and intelligent assistants that drive revenue retention, efficiency, and customer satisfaction. I also mentor engineers, codify standards, and partner with cross-functional teams to ship robust solutions.
