My strongest work is practical reliability engineering: stabilizing systems, cleaning up messy environments, automating repeatable operations, and leaving behind clear documentation so the next person can maintain the setup. I specialize in Linux server administration, production troubleshooting, operating system migrations, infrastructure automation, monitoring, storage work, virtualization, web hosting recovery, and cloud/VPS operations. I work with RHEL, AlmaLinux, SLES, Ubuntu, HP-UX, Solaris, AIX, Azure, AWS, IONOS, Hetzner, Hostinger, DigitalOcean, cPanel/WHM, Plesk, WHMCS, Docker, Kubernetes, KVM, Libvirt, Proxmox, VMware, MySQL, MariaDB, PostgreSQL, and DB2. I have handled 20-30 RHEL Leapp upgrades from RHEL 7 through 10, 20-30 SLES migrations from SLES 11 to 15, 5-10 AlmaLinux migrations from 8 to 10, Ubuntu 18.04 to 24.04 migrations, production fleets from a handful to hundreds of machines, Ansible and parallel Bash automation, high-availability sites handling thousands of connections per minute, delicate LVM2 storage migrations, Plesk/WHMCS recovery, and incident coordination with hosting-provider platform teams. I also work with practical AI infrastructure and local/self-hosted model tooling. My AI-related work includes Ollama, Open WebUI, LiteLLM, vLLM, SGLang, llama.cpp, SurfSense, JupyterLab, Caddy, Nginx, remote GPU hosts, OpenAI-compatible gateways, SSH tunnels to remote model servers, local model workflows, token-usage monitoring, AI gateway routing, coding-agent integration, Qwen/Ollama behavior control, prompt harness design, debug visibility, and compliance/retry loops. My work style is direct, practical, and evidence-based. I clarify the goal, inspect the environment, identify risks, build or fix in focused steps, test in realistic conditions when possible, deploy carefully, validate the result, and document the handoff path. I communicate clearly, prefer reliability over hype, and am fluent in English and Spanish. I am a strong fit for Freelancer.com projects involving Linux reliability, migrations, server recovery, hosting-provider infrastructure, Ansible/Bash automation, production troubleshooting, monitoring cleanup, self-hosted AI infrastructure, local model tooling, and practical workflow automation. less
