Things I’m working on or have worked on that seem worth highlighting.

KATDL

AI-Powered Solutions for Health Sciences. We partner with researchers, clinicians, and health organizations to build intelligent systems that advance patient care.

We’ve built a few systems worth highlighting:

  • Esophaguide - a scoring and visualization system for assisted diagnosis
  • An intelligent call schedule builder
  • An Agent Team Framework for building tailored AI agents
  • A graph based data and visualization framework

Subversive Software

Building hopeful, human-focused software that gives control back to people. We believe in privacy as a right, transparency by default, and technology that serves people. We build tools that give people visibility and help them understand how technology is being used around them better.

Examples include:

  • Tapped - a network visibility tool
  • Survey - a tool that makes it easy to see bluetooth, wifi and software defined radio
  • F0 - a Mac app for Flipper Zero
  • Flack - A browser extension that lays a trail of waste behind
  • Proxy - An alternative way to see what your computer is talking to
  • Webring - An easy way to share information across sites.

Jemurai

I founded and ran Jemurai for 12+ years. Jemurai was a security consultancy focused on helping companies build secure software. We built SecurityProgram.io — a SaaS platform to help organizations plan, track, and manage their security programs.

Jemurai was acquired by Crux in 2024.

Book: Building an Agile Security Program

I wrote a book for tech CTO’s or junior security folks to get a holistic view about approaching security in a startup environment.

IonQ

From 2021 until mid 2026 I was the Head of Security at IonQ, a publicly traded quantum computing company.

OWASP

Former Board Chair, Chapter Leader, and Project Leader for the Open Worldwide Application Security Project. OWASP is a nonprofit foundation that works to improve the security of software through community-led open source projects, hundreds of local chapters worldwide, and educational conferences. I helped lead the organization through a period of growth and modernization.
