About

Security-minded builder

I work with development teams, architects, delivery leaders, and security stakeholders to integrate security into the software development lifecycle. My background spans software engineering, DevSecOps, automation, secure design reviews, threat modeling, and vulnerability management.

I care about practical systems: tools that remove repetitive work, security guidance that engineers can actually use, and infrastructure that is understandable enough to maintain.
