About Andrei Dinu

I design and operate resilient Linux-based infrastructures and complex networks with a focus on security, performance and scalability. My work spans full-stack environments - from on-premise to public cloud - across media, telecom, and enterprise sectors. Highlights • Infrastructure lead for major Romanian media platforms including Pro TV, Antena Group, iaBilet, Gandul Media, RUN Data, and more - delivering secure, high-availability systems with CI/CD pipelines and observability built in. • Network architecture for SABMiller (Asahi), PepsiCo (QAB), La Fantana and more - secure, resilient and high-performance connectivity across data centers, HQs, and branches. • Backbone/core and multicast design at InterLAN Internet Exchange and NextGen ISP - including live TV and BGP peering optimisation. • Private cloud architecture - designing and deploying infrastructure from the ground up, including rack servers, blade systems, SANs, and enterprise storage. • DevOps expertise - implementing GitLab-based CI/CD pipelines, infrastructure as code with Terraform/OpenTofu, container orchestration with Kubernetes, and version control using Git. • SRE focus - scaling observability stacks like Zabbix, Grafana, Prometheus, ELK and more to monitor thousands of systems, applications, and network devices. Technical Stack • Cloud: Azure, AWS, GCP plus on-premise with Proxmox, OpenStack, KVM • IaC & Containers: Terraform/OpenTofu, Kubernetes, Helm, Docker, containerd • CDN & Edge: Cloudflare - DNS, WAF, caching, performance • Languages: Bash, Python, PHP, Ruby • Linux: Debian/Ubuntu, RHEL/CentOS/Rocky, Gentoo • Networking: Cisco, Nokia/Alcatel Lucent, Juniper, Arista - routing, multicast, security, IPv6 • Hardware: HPE, Dell, Supermicro servers, bladecenters, SAN storage Let’s connect if you’re building or scaling platforms that matter.
