I’m Roy.

I’ve always had a restless, childlike curiosity that forces me to get to the bottom of how things actually work.

I’m currently pursuing my Philosophy and Computer Science double major at the Open University.

Nature

What I do

Technically, I work in security research and software development. I specialize in:

  • Penetration Testing: End-to-end testing from a researcher’s perspective.
  • AppSec: Logical exploitation across Android, Web, Active Directory, and niche systems.
  • Code Audit & Debugging: A programming language polyglot. I can navigate, debug, and deconstruct large, sophisticated codebases in almost any language.
  • Development: Rapid PoC and prototyping, as well as focused, research-driven feature development. I use many languages, but Python is my strongest.

What I like

I have a particular intrest in these fields, to varying degrees:

  • Programming language & runtime internals.
  • Network protocol tunneling and bypass tricks.
  • Functional programming and cryptography.

Beyond the Logic

When I’m not deconstructing code or philosophy:

  • Salsa and latin dance: I love Salsa, and currently mastering my Cuban Casino style.
  • Bouldering: I am an avid boulder climber, mostly indoors in gyms, currently climbing ~V6. I love to mix it up with some calistentics and weights, and am currently attempting a handstand.
  • Freediving/ Apnea: I am a beginner freediver, with a PB of 22m both in CWT bifines and FIM, and static record of 3:30.
  • Solo Travel: I have traversed Latin America solo over a year, mostly over land with buses, hitchhikes and a lot of luck.
  • Languages: I am a polyglot, fluently speaking english, hebrew and spanish, with more planned.
  • Origami: I love folding paper sometimes. You can check out my latest work in my Origami Gallery.

I am an infamous dabbler, with few things I haven’t tried, from playing instruments, to sketching and doodle, collecting fountain pens, and whatnot :).

There is always more to learn, and I am here for it.
