Top SchoolDarren Schwarz is an Identity and Access Management architect and principal software engineer with over 20 years in IT, currently shaping IdAM strategy at dunnhumby after a transformative tenure at Flagstone.

His pragmatic innovation extends to open-source contributions that enhance authentication flexibility in IdentityModel and Duende projects, reflecting a commitment to community-grade tooling as well as enterprise-grade systems.
