Senior🎓
Top SchoolJoseph Yamada is a seasoned engineering leader with over two decades of hands-on experience and eight years focused on modern cloud-native delivery, currently leading Ontario’s OneID ConnectingOntario IAM platform supporting 197K+ clinicians. He specializes in high-scale identity and access (OAuth2/OIDC/SAML/SSO/token services), multi-cluster OpenShift reliability, and PHI-grade security, having driven measurable DORA improvements (3–5× deployment frequency, lead time cut from weeks to days, MTTR −40%) and 99.95%+ availability. Joseph blends systems design and RFC-driven architecture with pragmatic CI/CD, GitOps, and IaC practices that eliminated configuration drift and clarified service boundaries across complex federated workflows. A committed talent developer, he has mentored dozens of engineers and hired/mentored 70+ co-ops into senior roles, while authoring operational runbooks and an Architecture Build Book that codified multi-cluster reliability patterns. Practical, metrics-driven, and unusually attuned to both compliance and developer velocity, he converts security-heavy constraints into scalable, observable systems.
