About

Mobile security engineer and software architect with extensive experience in mobile security, digital identity verification and applied cryptography. I integrate NFC, cryptography and biometrics into mobile solutions with a focus on privacy, user authentication and legal compliance. I design systems for public institutions and private companies, and I teach the attack-and-defense craft behind them.
