My focus is driving growth through strategic partnerships, market expansion and the development of innovative, technology-enabled solutions that improve efficiency, resilience and client outcomes. With a career spanning sales, relationship management, product development and strategy, I offer a broad, cross-functional perspective backed by direct P&L ownership. I’m experienced in working with senior stakeholders across financial institutions, regulators and industry partners, turning strategic vision into practical, data-driven execution. I’m particularly passionate about the evolution of financial market infrastructure and the digital asset ecosystem, actively engaged with clients, platforms and regulators to help shape forward-looking, institutional-grade solutions.
