Elias
Frehner
Started as a precision machinist — obsessed with tolerances measured in microns. That obsession carried into software. Today I build at the intersection of secure architecture and elegant interfaces: full-stack development, penetration testing, and systems that work beautifully under pressure. Currently studying Computer Science, contributing to open-source, and going deep on x86 reverse engineering.
