Top SchoolKoichi Shiraishi is an experienced backend and DevOps engineer with 11 years building and hardening cloud-native systems, currently working on enabling teams at Gaudiy in Chiyoda, Japan. Previously he shaped reliability and architecture at Mercari/Merpay, moving from SRE into architect roles and focusing on production-grade infrastructure. A prolific open-source contributor and Gopher, Koichi has practical impact across high-profile projects like the Go toolchain, Docker Machine, BuildKit, gVisor and Delve, often improving cross-platform builds, low-level system code, and package management. His strengths lie in bridging low-level OS/runtime concerns with developer-facing tooling—patching macOS build issues, adding darwin vsock support, and maintaining Homebrew formulae and casks. Notably, he combines hands-on debugging and build-system fixes with automation and release work, demonstrating both deep systems knowledge and attention to developer experience.
