About Me
Site Reliability Engineer (SRE) and Solution Architect with 20+ years of experience building highly reliable, secure, cloud-native distributed systems.
Proven track record designing and operating high-concurrency microservices supporting 27M+ users,
with deep expertise in Kubernetes, CI/CD, Observability, Security, and Database performance optimization across AWS, Azure, and GCP.
Strong DevOps background, with hands-on backend engineering in Go and Node.js,
and experience in banking-grade identity integration, vulnerability assessment, and load testing.
I value continuous learning in system design and enjoy driving business success through efficient, well-crafted technical solutions.
Secondary Interests
Beyond core engineering, I am always interested in Domain-Driven Design (DDD) and building secure distributed architectures. Outside of tech, I enjoy active pursuits like swimming, camping, and the artistic storytelling found in Japanese manga.
