Computer Scientist ·ETH Alumnus ·McKinsey Alumnus

I am a technologist drawing on over a decade of experience in enterprise architecture, software engineering, and systems design to help organizations across the private, public, and social sectors identify emerging business opportunities, adopt a data-driven mindset, and apply cloud computing technologies. As a senior consultant at McKinsey & Company, I advised C-level executives on technology-related topics to help them solve their most pressing challenges. I prepared multi-year business transformations, designed modern IT architectures, and lead the implementation of many complex information systems in the cloud and on premise. During my doctoral studies at ETH Zürich, I developed cutting-edge technologies that have had a substantial impact on large-scale data management and distributed data processing. I authored several peer-reviewed publications presented in international research venues, and worked with multiple partners from industry and academia on innovative projects to accelerate database systems, make existing processes more efficient, and improve overall business insights.
