Top expert inCloud-Native DevOps with Kubernetes
John Howard is a Senior Architect with 11 years of experience designing and hardening cloud-native infrastructure and service mesh systems, currently leading architecture at Solo.io after a multi-year stint driving Istio development at Google. He blends deep backend and DevOps expertise—improving build/release pipelines, protobuf generation, and test infra—with hands-on contributions to marquee open-source projects like Istio, Envoy, and Kubernetes. His work frequently targets reliability and automation at scale, from presubmit/postsubmit CI jobs and caching fixes to performance-sensitive client-go and apimachinery optimizations. Comfortable across roles from technical writing to backend development and automation, he often surfaces subtle maintenance wins (e.g., escaping GCS uploads, reducing spammy logs) that materially improve large projects. Based in Livermore, CA, he pairs pragmatic engineering with community stewardship, authoring documentation, tests, and org-level automation that keep complex ecosystems healthy and reproducible.
