About

A technical career shaped by building across disciplines.

My work sits at the intersection of AI, engineering, and business transformation. I have helped organizations design enterprise AI solutions, modernize cloud and data platforms, and translate emerging technology into systems that teams can actually operate and trust.

What makes my background different is the range. I have built client facing AI accelerators, delivered large scale enterprise programs, and founded a quantitative trading platform where infrastructure, signal quality, and execution discipline mattered every day. That mix gives me a practical perspective on architecture, delivery, and value creation.
