I build and operate
production infrastructure
DevOps engineer experienced in Kubernetes, Infrastructure as Code, CI/CD, cloud networking, observability and data/AI-platform infrastructure.
Most recently: almost two years at Sber in the GigaData team, working with Cloud.ru Advanced and Evolution. Earlier: self-managed Kubernetes in on-premise environments.
