Building software — and breaking it to make it safer.
about me
I'm David Zettler — a software engineer and security researcher based in Zurich, Switzerland. I build across layers — web, desktop, low-level — and take systems apart to understand how they fail. That second habit makes the first one better: software that is clear, fast and hard to break.
