Rockstar🎓
Top SchoolQuentin Machu is a seasoned infrastructure and backend engineer with 11 years of experience building low-latency, highly available systems for finance and cloud-native platforms. He led global DevOps organizations at BitMEX and Hilbert Technologies, architecting HFT networks, multi-continent failover, and IaC practices that reduced trade latency by orders of magnitude. An early open-source creator, he conceived Clair—the widely adopted container-vulnerability scanner—and has deep expertise optimizing database transactions and avoiding deadlocks in projects like Cayley and Clair. Quentin blends hands-on systems programming and release automation with operational rigor—designing CI/CD, PKI, and security controls at scale—while also founding and exiting a high-availability hosting business. He brings a rare mix of trading-grade networking, Kubernetes/automation experience, and pragmatic database engineering focused on performance and reliability.
