I'm a technology executive and software engineering leader with 28+ years of experience in digital banking, fintech platforms, and large-scale cloud transformation. I've spent my career at the intersection of engineering excellence and business impact.

At Citigroup, I lead the Digital Engineering organization for Citi Retail Services — responsible for the Fusion Digital Platform serving 70M+ credit card accounts across 30+ iconic brands including Best Buy, Macy's, The Home Depot, and ExxonMobil.

I'm passionate about AI-driven engineering productivity, cloud-native architecture, and building high-performing global engineering teams that deliver measurable business outcomes.
