Hi, I'm Gerald — a Cybersecurity Researcher focused on exploiting and hardening the Linux operating system.

My work involves reverse engineering, vulnerability research, and building tools that interact directly with the kernel and system internals. I thrive where most abstractions break down — at the interface between hardware, OS, and application.

This blog is my lab notebook: a curated collection of write-ups, technical deep dives, and research experiments from my journey through offensive security.

Whether you’re here to learn, collaborate, or explore the inner workings of Linux with me — welcome! Curiosity is the only requirement.
