About
I am a systems programmer and security engineer working at the intersection of low-level software, network protocols, and vulnerability research.
My work focuses on understanding how systems actually behave under real conditions — through reverse engineering, protocol analysis, and adversarial testing — then feeding that understanding back into tooling and upstream improvements.
Focus Areas
- Low-level systems (Linux, kernel interfaces, performance tuning)
- Network protocols and traffic analysis
- Vulnerability research and exploit development
- Security tooling and automation
Approach
- Reverse engineering over assumptions
- Reproducible research and verifiable results
- Upstream-first contributions where possible
- Minimal, composable tooling
