What I'm looking for

I seek roles focused on Linux infrastructure, automation and cloud where I can lead migrations, improve reliability, and work in small high-performance teams with opportunities for certification growth.

linux sysadmin and devops with more than 15 years working in enterprise IT environments, mainly focused on Linux infrastructure, automation, and platform operations.

Currently working at DEKRA, managing over 100 RHEL and Rocky Linux servers, maintaining containerized environments, and supporting internal platforms based on Kubernetes, Docker, Podman, and Ansible.

Most of my daily work involves system administration, CI/CD pipelines with GitLab, monitoring and observability using Grafana, Prometheus, and Zabbix, container deployments andd AI infrastructure running on-premise with Ollama and Open WebUI on RHEL 9 using NVIDIA GPU passthrough.

I hold the LPIC-1 certification and I’m currently preparing for LPIC-2 while continuing to improve my Kubernetes and Infrastructure as code skills through the lemoncode devops bootcamp.

I enjoy improving infrastructure reliability, automating repetitive tasks, and building systems that are easier to maintain and monitor.

Open to remote opportunities in DevOps, Platform Engineering, or SRE roles.

Based in Málaga, Spain (CET/CEST).
