I build and direct AI-driven offensive security tooling.

Projects

Open-source tools I've built.

AppSec Galaxy AI-powered security scanner (Semgrep, Gitleaks & Trivy) with cross-file attack-chain analysis and automatic code fixes, delivered via PR of course. 🙂 SAST Secrets SBOM AI Remediation Polaris Home-network security monitor that discovers every device, maps your network topology, and port-scans for risky exposure. No router login, no agents, no cloud. Network Security TypeScript React Local-first Onion Lens Passive OSINT tool that puts an AI correlation layer over dark-web search engines. Ask in plain English, get clustered findings with extracted entities and scam flags instead of a raw keyword dump. Metadata only, no Tor required. OSINT Threat Intel Python AI Analysis Clear Skies Astrophotography alert bot that scores dozens of deep-sky targets against hourly weather, altitude, and moon interference, then pings my phone when tonight is worth setting up the telescope. Astrophotography Python Automation Push Alerts

About

I'm a Senior Application Security Engineer based in the Tampa Bay area, specializing in offensive security, AI-first development, and secure software engineering.

With 10+ years in security, including an early stretch in the Intelligence Community, I work alongside software engineers to find and prove real weaknesses, then help fix them without slowing delivery.

At Las Vegas Sands, I build the offensive tooling our team uses to find and prove real weaknesses in applications, infrastructure, the software supply chain, and AI systems. Most of that tooling is written by AI agents I direct, so a big part of the job is context engineering, keeping a human in the loop, and owning the results. My daily workflow pairs Claude with Burp and Kali.

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, cheering on the Tampa Bay Lightning, chasing national parks, or spending time with family.
