Top SchoolGreg Orzell is a Principal Software Engineer with 14+ years building highly available, cloud-native distributed systems for companies from Netflix to GitHub. He was a key architect of Netflix’s datacenter-to-cloud migration and co-founded the Simian Army open-source chaos engineering tools, demonstrating deep expertise in fault tolerance, JVM performance and scalable infrastructure. At GitHub he has driven high-availability engineering and the new code search engine while previously leading architecture and engineering teams through cloud migrations and big-data streaming efforts. Greg blends hands-on backend contributions—recent work includes monitoring, orchestration and Azure Blob support in popular open-source repos—with executive-facing strategy on organization design and operational culture. Based in Mainz, he pairs practical system-level coding and refactoring with a track record of shaping resilient platforms and engineering organizations. An uncommon detail: he started his career in 24/7 operations and continuous-integration tooling, which informs his pragmatic focus on operability and observable systems.
