Danny Kulchinsky is a Principal Site Reliability Engineer based in Canada with nine years of focused experience building and operating resilient, high-performance infrastructure. He has led platform and SRE work at Fastly and Telefónica, architecting Kubernetes clusters, traffic-shifting blue/green strategies, and Prometheus-based observability integrations. Danny contributes to prominent open-source projects like kubespray, where his networking and security-focused patches improved production readiness for Kubernetes deployments. His background spans infrastructure-as-code, load balancing, log pipelines (EFK), and automation—skills he combines with hands-on troubleshooting and performance analysis. Known for bridging deep technical expertise with cross-team collaboration, he also has experience shaping cloud transformation roadmaps and implementing regulatory-compliant architectures. Unusually for an SRE, he pairs telecom-grade systems design and VoIP experience with modern cloud-native practices, giving him a broad systems perspective.
