Good projects take a minute.

I am rebuilding this section around work that is current, useful, and worth explaining properly. Old proof-of-concepts are staying in the workshop until they earn a spot here.

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.
