I’m a Site Reliability Engineer based in Burgos, Spain. I design and operate resilient infrastructure for systems that need to stay up.

Currently I lead infrastructure at Derecho.com, where I’m responsible end-to-end for a hybrid cloud platform spanning AWS, Hetzner, and Proxmox, modernizing a stack with 25 years of history. I’ve migrated legacy servers from Debian 7 to Debian 12/13, built out Terraform/OpenTofu with Terragrunt, written 30+ Ansible roles, established secure inter-environment communication via redundant WireGuard tunnels, and deployed observability with Prometheus, Grafana, and Loki. I have implemented a GitOps methodology on K3s using ArgoCD and secret management with HashiCorp Vault.
