Profile

Specialized in cloud infrastructure and DevOps, with 11+ years across software development, operations and security. I design and operate complex platforms — Kubernetes (CKA certified), Kafka, GitOps — and maintain the critical tools teams rely on: GitLab, ArgoCD, HashiCorp Vault, Keycloak and the Prometheus stack. Pursuing the CEH certification, I focus on automated, resilient SOC infrastructure: quarantine, forensic analysis and fast recovery. I also run my own IPv6-only autonomous system (AS214587).
