/About

I am a Security Engineer with a specialization in cloud security and DevSecOps automation. I implement policy-as-code frameworks and secure CI/CD pipelines that enforce least-privilege access while ensuring that developer workflows remain fast and frictionless.

My primary focus is on embedding security guardrails that identify issues early, all without hindering innovation, making the failure modes visible, the recoveries fast, and the engineering ergonomics good enough that the security work sticks.
