Tom Herman

Cyber Researcher and low-level R&D Engineer

I take things apart to see how they actually work. That's my job, and it's how I spend my weekends — which is how a language with a single instruction came about, along with a C compiler for it and an offline Wikipedia on my watch. I studied Software Engineering at Technion in 2017–2021 and haven't stopped since. Give me technology and a real challenge, and I'm in.

Experience: 5 years in the field, since 2021
Works with: C · C++ · Python · assembly · reverse engineering · OS internals

FlipJump

A Turing-complete language built on one instruction — flip a bit, then jump. And the ecosystem I built around it.
