🐡 System Security Researcher | Low-Level & Kernel-Focused Developer 🐧

Typing SVG

Auditing kernels and inspecting memory — one syscall at a time.
Mostly learning by breaking things and figuring out why.

📔 About Me

I'm a self-taught developer focused on system security and low-level behavior.

I didn't come from a formal background in this area — most of what I know came from curiosity, reading documentation, breaking systems in VMs, and trying to understand what actually happened under the hood.

I like working close to the system boundary — where abstractions stop helping and you have to deal with memory layout, process behavior, and real execution flow.

Instead of relying on large frameworks, I prefer small and transparent tools written in C and Bash, where I can see exactly what is happening.

Projects like K-Scanner, LinSpec, S.I.R.E.N, and OpenSec come from that mindset — building simple tools to observe, validate, and question how systems behave in real conditions.

Most of what I do follows a few ideas:

  • Push systems until edge cases start to show up
  • Keep things minimal and inspectable
  • Focus on real behavior instead of assumptions

Security, for me, isn't about running tools — it's about understanding what the system is actually doing when things start to break.
