Chad Parnin

Hello Earth. I'm a Senior Cybersecurity Engineer based in the Tampa Bay area, specializing in application security, penetration testing, and AI-assisted development & security.

With 10+ years across the Intelligence Community and the private sector, I work alongside software engineers to secure the systems that matter, building practical, drama-free security programs that help teams ship confidently and securely.

At TekStream, I build and scale AppSec programs, architecting CI/CD-integrated scanning across 500+ repositories and dozens of teams, advising executives on tooling and risk, and creating educational content.

I also built an appsec tool that does everything I've always wanted, AppSec Galaxy, and have custom AI workflows that pair Claude with Burp and Kali for pentesting.

I hold a Master's in Cybersecurity Technology, a B.S. in Computer Science from Indiana University, and certifications including GPEN, GCIH, CEH, Security+, and ITIL.

Off the clock you'll find me on the golf course, doing astrophotography, playing chess, doing yoga, cheering on the Tampa Bay Lightning, chasing national parks, or spending time with family.
