I am a security researcher and infrastructure engineer focused on the weird places where hardware, radio, timing, and software meet.

My work sits at the intersection of physical-layer security, software-defined radio, network infrastructure, and defensive engineering. I am especially interested in systems that most people treat as background assumptions: GPS timing, RF links, embedded receivers, protocol edge cases, and the quiet infrastructure that keeps networks and organizations moving.

My current research focuses on GPS and GNSS security, including timing manipulation, receiver behavior, navigation-message parsing, and localized RF exploitation. I build small labs with real hardware, SDR tools, custom parsers, and declarative environments so I can test ideas repeatably instead of relying on hand-wavy theory.

Background

Before moving deeper into cybersecurity and infrastructure engineering, I spent 12 years in the U.S. Army: four years working in communications and eight years working in a weapons-focused role. That background shaped how I approach technical problems: understand the system, test assumptions, reduce noise, and keep the solution practical.

Professionally, I work across infrastructure, cybersecurity, automation, and systems design. I have supported public-sector environments, built resilient business networks, operated consulting work through private organizations, and developed custom tools when off-the-shelf software was too bloated, fragile, or expensive for the job.

Current Focus

My current work and research include:

  • GPS/GNSS security, timing integrity, and receiver behavior
  • Software-defined radio and RF security research
  • Network infrastructure, identity, and defensive operations
  • Declarative lab environments with NixOS and reproducible tooling
  • Custom software for security, operations, and offline workflows
  • Practical threat modeling for obscure but real attack surfaces

This site is where I publish research notes, project writeups, and technical experiments. Some of it is polished. Some of it is a lab notebook with better punctuation. The common thread is curiosity about systems that look boring until they fail, leak, drift, parse something strange, or trust the wrong signal.
