Currently working as a Senior Site Reliability Engineer in the Platform SRE team at Shopify 🛍️, focusing on resiliency in critical workloads through chaos testing, database resiliency, AI-powered improvements, and on-call incident response across the globally distributed team.

Throughout my career, I've focused on SRE and operational excellence with 9+ years of industrial experience, covering CloudNative areas such as Kubernetes, Go, and Software architecture.

Also, I am a tech speaker who's given 60+ conference/event presentations about SRE, CI/CD, Pattern language, AWS, Terraform, TDD, etc. Additionally, I contributed to 2 industrial magazines, where I wrote the chapters covering Docker chapand the unit test best practices.

I spent many years in the E-commerce and financial domains until my current role. My first engineering job as a full-time engineer was in cloud infrastructure with AWS. Then, as a backend engineer, I joined the payment team at BASE, one of the biggest E-commerce platforms in Japan. After that, I was transferred to a subordinate company that offered financial services at an early stage as a first engineer. I was promoted to Tech Lead and Engineering Manager of 10 team members. After that, I worked as a Senior Site Reliability Engineer at Autify, a Series B startup headquartered in San Francisco, which serves AI-powered quality assurance platforms. I was mainly responsible for developing and operating complicated infrastructure systems for business and maintaining our cloud-native platforms such as Kubernetes, AWS, and Google Cloud.
