Top SchoolYury Tsarev is a Principal Solutions Architect and founder with 15+ years building resilient, cloud-native infrastructure and global traffic control for large enterprises. He created k8gb, a CNCF project for Kubernetes global load balancing, and now scales Crossplane-based control planes at Upbound while co-founding 0ttl to productize intelligent global traffic orchestration. Deep in DNS, controllers and operators, he contributes to external-dns and multiple Crossplane AWS providers, often implementing IAM, health checks and failover strategies that harden multi-region deployments. Yury combines hands-on backend and DevOps engineering with platform leadership at banks and consultancies, delivering production-grade SRE and platform tools. Based in Prague, he sits at the intersection of open source and commercial productization and advises startups like Mind Bank AI on cloud-native infrastructure. An applied mathematics graduate, he鈥檚 as comfortable designing CRD controllers as he is explaining global resilience trade-offs to execs.
