About Me
I’m a security-focused engineer who thrives where infrastructure, automation, and security meet.
I build secure, scalable systems across AWS, GCP, and Kubernetes, with a passion for IAM, auditability, and cloud-native best practices.
Over my career, I’ve designed tools that not only strengthen security posture but also improve developer efficiency—like Kubernetes controllers for resource lifecycle enforcement, Slack-based secure automation bots, and cryptographic signing services with compliance traceability.
I adapt quickly to new problem spaces, balance speed with precision, and bring a collaborative mindset to every project. My goal is simple: deliver secure, reliable systems that empower teams and protect business value.
