Summary
👤
Senior🎓
Top SchoolJonathan Oddy is a Principal Engineer based in London with 14 years of experience building cloud-native platforms, observability, and high-availability systems across AWS and GCP. He led early Kubernetes production rollouts and service mesh work at Wise, authored a Java control plane for Envoy, and more recently built a GCP-based PaaS for JPMorgan Chase UK that met strict enterprise controls. Comfortable in low-level and high-level languages (Java, Go, C, PHP, Perl, bash) and Linux internals, he combines systems and platform engineering with pragmatic product thinking. An active open-source contributor, his patches to Envoy and SPIRE focus on robustness and secure service discovery—work that directly improves service mesh reliability. He’s equally at home debugging TCP/TLS/CDN performance as designing platform governance, and often surfaces subtle production race conditions before they hit users.
