Nels G.

I harden and scale RHEL/Ubuntu fleets with Ansible and build Proxmox & K8s clusters. I fix incidents fast then automate the fix so it doesn’t return. 12+ years in Linux/DevOps and security. I design, migrate, and stabilize critical systems for SMBs and enterprises (cloud and on-prem). I turn vague problems into a crisp plan, then ship working infrastructure with docs and handoff. Core work I do - RHEL 7/8/9 hardening (CIS-aligned) with reusable Ansible roles - Proxmox installs, VM templates, Proxmox Backup Server (PBS) backups, networking/VLANs - Kubernetes/MicroK8s setup, ingress, TLS, GitOps-friendly layouts - Monitoring: Prometheus + Alertmanager + Grafana dashboards/alerts - Red Hat toolchain: Satellite (content mgmt/patching), Ansible Automation Platform/Tower (RBAC, job templates), OpenShift install/admin, Red Hat IdM/FreeIPA - Automation & CI/CD: IaC (Terraform), pipelines, secret handling - Migrations: lift-and-shift to new hosts/clouds, zero/minimal downtime
