Roald Nefs

Chief Technology Officer at Warpnet

CTO at Warpnet, a decade deep in security and platform engineering, and co-organizer of BSides Groningen, BSides Amsterdam, and Cloud Native Groningen. Active open source contributor with a current research focus on automotive security, though on any given weekend he's just as likely to be tinkering with AI, reverse engineering an animal microchip, or soldering conference badges at 2am.
