Profile

At 10 I earned my first Bitcoin. At 15 I was bypassing SSL pinning on mobile apps. At 16 I reported a critical vulnerability in the Danish Railways. At 20 I shipped the first non-custodial MPC wallet for an entire blockchain network. Computer Science student at the University of Copenhagen with production experience across cybersecurity, blockchain engineering, firmware reverse engineering, and full-stack development. Self-taught from day one. MIT xPRO and Google Cybersecurity certified.
