About Andrei

I am a Web Architect and Security Researcher focused on building resilient digital ecosystems. With a deep background in Drupal 11 and full-stack JavaScript, I bridge the gap between high-performance development and rigorous security standards.

My work revolves around the intersection of architecture and defense. Whether I'm designing decoupled enterprise platforms or conducting penetration tests on SaaS infrastructures, my goal is always to create systems that are as secure as they are functional.
