(Kirubel)

Sup, I am a security researcher and a software engineer. I love to break things and just see how and to what level they function. I mostly focus on offensive security at low-level to check if I can get a buffer overflow on the software, and develop apps, websites, and APIs. On my free time, I try to make some digital arts like 3D designs, posters and drawings.

CH.01 The Work

I break things to understand them, then build them back stronger.

Everything I've made (The Undeleted Ones), audited, or contributed to is open-source. Click any project to view its repository on GitHub.

CH.02 The Craft

Between the binaries, I make things that don't need to compile.

Live Render — The-Donut Spinning

C++ · ASCII · 1.7 KB 80 × 22 chars Z-buffered torus View Source

Off-screen work. When I'm not auditing binaries I'm pushing pixels — 3D renders, poster compositions and digital drawings. Click any piece to see it full size.

CH.03 Live Signals

The systems keep running while I sleep.
