What I'm looking for

I seek a security-focused role where I can embed DevSecOps practices, automate testing, mentor teams, and measurably reduce vulnerabilities while enabling developer productivity.

I am an application security engineer with extensive experience embedding security into CI/CD pipelines, implementing IaC scanning, and conducting comprehensive web application penetration testing across internal and external applications. I lead developer-focused shift-left initiatives, created security guides and training, and served as a security point of contact for 100+ employees while reducing security findings and manual review time.

My background includes senior system and field engineering roles supporting servers, networks, and endpoint environments, scripting automation with Python, PowerShell, and SQL, and contributing to open-source projects like HT3D4ALL. I prioritize pragmatic security solutions that enable developer productivity and measurable reductions in vulnerability exposure.
