Cybersecurity-focused technologist that likes building secure, automated, and intelligent systems across cloud, software, and infrastructure layers. Operating at the intersection of security engineering, cloud platforms, and automation.
Focused on eliminating manual security gaps by embedding controls directly into infrastructure, pipelines, and applications. I leverage and implement AI-driven tooling where it makes sense, improving detection, response, and decision-making at scale without adding unnecessary complexity.
