Summary
🤩
Rockstar🎓
Top SchoolNaoya Matayoshi is a Staff Support Engineer with 11 years of experience who blends a developer-first mindset with deep expertise in CI/CD, Kubernetes, and distributed systems. He began his career building Rails applications and helped turn prototypes into production products, later contributing technical writing to major Japanese Rails resources like railsguides.jp. At CircleCI he investigates complex self-hosted and cloud CI/CD issues, authors fixes and validation, and builds AI-assisted investigation workflows that accelerate support. Fluent in Japanese and English, he excels at debugging cross-service problems and translating customer insights into engineering improvements. Less obvious: his background as both an in-house product developer and a hands-on support engineer gives him rare empathy to dig into code-level root causes rather than just routing tickets.
