Specializing in secure cloud architecture, container security, and DevSecOps practices. Building resilient, compliant, and secure infrastructure at scale.

About Me

My journey in DevSecOps and cloud security

Xin chao, I'm 

I'm a DevSecOps engineer with deep expertise in building secure, scalable cloud infrastructure. Over the years, I've evolved from systems engineering to specializing in the intersection of development, security, and operations—helping organizations implement secure by default practices.

My focus is on designing and implementing cloud-native security architectures, hardening Kubernetes clusters, establishing secure CI/CD pipelines, and ensuring compliance with industry standards. I believe security should be embedded in every layer of the infrastructure, not bolted on as an afterthought.

I'm passionate about infrastructure as code, automation, and reducing security risks through proactive threat modeling and continuous security scanning. When not securing infrastructure, you'll find me contributing to security-focused open source projects or speaking about DevSecOps best practices.
