Building Security for People, Not Companies
My journey began at age 9 with a Commodore 64, learning that computing could be joyful, creative, and empowering. The "computers for the masses, not the classes" philosophy shaped my approach to security: building systems that protect people while preserving the open, innovative spirit that makes technology transformative. Today, I carry that builder's spirit forward through projects like the C64 Arcade, while helping organizations create security architectures that enhance rather than restrict user agency.
