Top SchoolGuillaume Le Biller is a Principal Blockchain Platform Engineer with 13 years of experience designing and operating secure, enterprise-scale cloud and on-premise platforms. He specializes in Kubernetes, Terraform, and AWS, and currently runs production Cosmos validator fleets, builds a Kubernetes Go operator for blockchain nodes and IBC relayers, and leads a team automating blockchain services on GCP. Previously he led infrastructure and platform at Traveldoo/Expedia Group, driving a migration of 150+ apps to AWS, scripting compliance automation, and scaling systems to handle millions of daily requests while shrinking RTO/RPO dramatically. A pragmatic engineer who started in software development, Guillaume combines hands-on coding (Golang, VueJS, Cosmos SDK) with platform architecture and coaching, reducing deployment times to minutes and MTTD to under two minutes. He is an active open-source proponent with contributions to major tooling and a track record of operationalizing high-security, audit-compliant systems. Outside work he’s an explorer—14 countries and counting—and a recent amateur dancer, reflecting a curious, continual-learning mindset.
