Shirou Wakayama is a Chief Architect and distributed-systems engineer with over 15 years of hands-on experience delivering production-grade IoT and cloud platforms across regulated domains. He designs end-to-end solutions—from embedded firmware and secure device identity to telemetry pipelines and cloud monitoring—that operate reliably over unreliable networks such as maritime links. Previously he led architecture for a regulated online brokerage and now builds resilient systems for commercial fishing vessels, combining operational on-call ownership with regulatory-compliant reporting and anomaly detection. Shirou is the creator and long-term maintainer of gopsutil, a widely adopted Go system-monitoring library, and contributes to notable open-source projects like Sphinx, Telegraf, and ANTLR, demonstrating depth across tooling, telemetry, and language runtimes. He focuses on systems that must survive real-world failures rather than just pass demos, blending pragmatic engineering with strong observability and operational practices. Based in Tokyo with a Keio University master’s background, he brings rare cross-domain experience spanning embedded, edge, and cloud.
