I build and operate production infrastructure where Kubernetes, cloud, and automation meet — deploying containerized platforms, wiring up CI/CD, and keeping it observable and secure. Top-Rated with a 100% Job Success Score. I run live workloads today (Kubernetes with Rook/Ceph storage, Docker, monitoring with Prometheus/Grafana/Loki, WireGuard-secured access), so I deploy what I actually operate — not theory. Most infrastructure jobs aren't a single tool; they're a stack. A Kubernetes deployment that needs AWS underneath it. A container platform that needs CI/CD, monitoring, and a hardened network perimeter around it. A migration where the firewall and VPN have to hold through the cutover. That convergence is what I do — and the network-security depth beneath it (firewalls, VPNs, segmentation) is the difference between a platform that merely runs and one that stays secure and reliable under real traffic. ⚙️ Kubernetes & Containers Production Kubernetes deployment, scaling, and orchestration Rook/Ceph distributed storage for stateful workloads Docker containerization, Compose, and Swarm Container registry, ingress, and microservices deployment Cluster hardening: RBAC, network policies, TLS ☁️ Cloud & Hosting (AWS, Azure, GCP, Hetzner, OVH, Digital Ocean) AWS: EC2, VPC, subnets, IAM roles and policies, security groups Infrastructure-as-Code with Terraform Proxmox/PVE deployments on Hetzner, OVH, and bare-metal providers Cloud migrations and hybrid on-premise-to-cloud connectivity Multi-cloud and bare-metal architecture 🚀 DevOps & Automation CI/CD pipelines: GitLab CI, GitHub Actions, Jenkins Automated deployment workflows and Infrastructure-as-Code Observability: Prometheus, Grafana, Loki Reverse proxy (NGINX), secrets management, TLS automation 🖥️ Virtualization & Migration Proxmox VE high-availability clustering with ZFS/Ceph Proxmox Backup Server, disaster recovery, backup strategy VM migration: VMware-to-Proxmox, Hyper-V, P2V Capacity planning and performance optimization 🔒 Network Security & Firewalls pfSense/OPNsense firewall deployment, optimization, and hardening VPN: WireGuard, IPsec, OpenVPN — site-to-site and remote access Enterprise network design, VLAN segmentation, zero-trust IDS/IPS (Suricata/Snort), traffic filtering, QoS Cisco/MikroTik/Ubiquiti — routing, switching, and network security 🎯 Why work with me Top-Rated, 100% Job Success, with a deep Cisco networking and security background — CCNA, CCNP, and CCIE (Routing & Switching) certified, with my deepest hands-on focus now on infrastructure, cloud, and automation built on that foundation.
