Dejan Lazar

Senior DevOps / SRE engineer with 15+ years running production infrastructure in high-stakes, regulated environments — cryptocurrency exchange (Bitstamp), licensed online gaming, and a NATO information system that I designed and brought through national security accreditation. Hands-on across the full stack: cloud (AWS, Azure, GCP), Kubernetes and Docker orchestration, Terraform and Ansible automation, CI/CD pipeline design, and observability with Prometheus, Grafana, Loki and ELK. Comfortable owning production end-to-end and communicating directly with clients, regulators and management.
