Summary
🤩
Rockstar🎓
Top SchoolStewart Butler is a Principal Engineer based in San Jose with nine years of hands-on experience building cloud-native infrastructure and developer tooling. He has driven core Istio improvements at Google—stabilizing manifest generation, refining CNI repair in istioctl, and fixing init-container ordering—demonstrating deep expertise in Kubernetes install/runtime behavior and reliable diffs for operator workflows. At Aviatrix he now applies that backend and DevOps pedigree to production networking and cloud platform challenges. Earlier roles span SRE and cloud migrations at Cybraics and large-scale ETL and async systems at athenahealth, where he significantly cut failure rates and sped report execution for thousands of clients. He pairs low-level systems craftsmanship (from embedded robotics and UAV prototyping at Georgia Tech to firmware and hardware work) with pragmatic production engineering. That blend of open-source contribution to a high-profile project and broad systems experience makes him adept at turning tricky platform problems into stable, observable solutions.
