Garrett Stimpson

I'm a Senior Cyber Security Analyst and software engineer with a background shaped as much by technical depth as it is by personal resilience. Over the years, I've built a strong foundation across software development, infrastructure, and offensive security-working extensively with PHP, Java, Kotlin, Python, C#, SQL, and modern web technologies like TypeScript, CSS, and jQuery. My systems experience spans Apache, Nginx, and Linux distributions including Ubuntu and Debian, along with deep involvement in automation, scraping, and scalable backend design.

On the development side, I specialize in Android engineering, where I've designed, built, and maintained production-grade applications using modern architectures and tooling such as MVVM, ROOM, Clean Architecture, and dependency injection frameworks like Dagger and Dagger 2. I focus on building software that is not just functional, but reliable, maintainable, and secure by design.

In parallel, I've developed extensive expertise in cybersecurity and penetration testing. I currently operate at a senior level, leading and contributing to advanced offensive security engagements. My experience includes over 1,000 completed full-scope penetration tests for organizations across North America, as well as internationally in regions including Sweden and other parts of Europe. My work spans web applications, infrastructure, and internal networks-covering everything from Active Directory exploitation and privilege escalation to Linux subsystem analysis, misconfiguration discovery, and post-exploitation workflows.

I also have hands-on physical penetration testing experience, assessing real-world security controls beyond the digital layer. This includes access control weaknesses, on-site attack vectors, and the intersection between human behavior and technical systems-an area often overlooked but critical to true security posture.

My path into this field wasn't conventional. It's rooted in redemption, discipline, and a commitment to a different way forward. After overcoming one of the most difficult chapters a person can face, I made a conscious decision to rebuild-anchored by a personal code, an oath to integrity, and relentless self-improvement. I've now been sober for nearly a decade, and that journey continues to define how I approach both life and work: with clarity, accountability, and purpose.

Today, I bring that same mindset into every system I build and every environment I test-focused on strengthening security, solving complex problems, and helping organizations understand where they are vulnerable before someone else does.
