About

I secure what others build — and build what others can't break.

I work at the intersection of security and engineering. My focus is on making systems resilient by design — hardening infrastructure, auditing code, and automating defenses before threats become incidents.

I care about building things that are correct, performant, and secure from the ground up. Whether that's a containerized security lab, a hardened production server, or a clean API — the standard is the same.

Selected Projects

A look at what I've built, broken, and hardened. Each project reflects how I think about security and software.

National Infrastructure Hardening

Designed and enforced server hardening baselines for mission-critical government systems. Deployed containerized security tooling, automated monitoring with Python/Bash, and architected secure remote access aligned with Zero Trust principles.

Virtualized Cybersecurity Lab

Designed and built a containerized platform for safe penetration testing and security research. Uses Docker and Linux network namespaces to isolate attack/defense environments for skills development.
