Security Architect | AI Security | Cloud Security | Identity | Governance

I am a security architect working across cloud security, identity, AI security, and practical governance. My day-to-day work often sits between architecture, engineering, compliance, and prototyping: translating risk into systems that teams can actually operate.

This blog is a long-running notebook for that work and for life around it. I write about security architecture decisions, LLM and agent security, Zero Trust, IAM and non-human identity, cloud governance, small engineering experiments, and travel notes collected with my family.

Current Focus

• AI Security, especially LLM and agent risks
• Zero Trust, IAM, and Non-Human Identity
• Cloud security architecture and governance
• Security as Code and repeatable control implementation
• Turning security ideas into small, testable prototypes

Credentials

• CISSP
• AWS Solutions Architect Associate

Writing Themes

• Security thoughts from real architecture work
• Notes on tools, systems, and small technical projects
• Family travel logs, mostly Japan and everyday observations

The tone here is intentionally simple: think clearly, write honestly, and keep enough context for the future self who has to read it again.
