What I'm looking for

I seek leadership roles building trustworthy, production-grade AI—leading model governance, mentoring teams, driving product innovation, and delivering measurable business impact within collaborative, compliance-focused organizations.

I lead AI and data science initiatives, building LLM-based products, advanced NLP systems, and deep-learning fraud detection that drove revenue growth and earned internal awards and multiple patents. I have led enterprise model governance, designed validation frameworks, and worked cross-functionally to deploy production-ready AI with regulatory and risk alignment.

I mentor technical and business teams, set AI/ML strategy, and drive research into state-of-the-art algorithms, MLOps, and alternative datasets to create trading insights and scalable analytics products. I turn complex data problems into reliable products that balance technical excellence with measurable business impact.
