I think in attack paths. I build in defense. I automate everything in between.

Security engineer building AI systems. MEng Cybersecurity at the University of Maryland. My work sits at the intersection of application security, cloud architecture, and LLM-driven automation, building systems that are both capable and defensible from first principles.

I've built kernel-level rootkits to understand evasion at the syscall level, designed multi-layer security platforms in Rust, implemented end-to-end encrypted communication stacks for automotive ADAS systems, and architected AI pipelines that process hundreds of sources into actionable intelligence daily.

Current focus: Meridian, a multi-agent intelligence system that filters signal from high-volume information streams and delivers what actually matters, when it matters.
