About Juanjo
I help businesses ensure their infrastructure is stable, secure, and cost-efficient.
Why work with me? I bring a versatile and cross-functional profile. I blend the technical depth of a classic SysAdmin with the agility of modern Cloud Operations. I understand infrastructure from the Linux Kernel up to Kubernetes orchestration, allowing me to solve complex issues that narrower profiles might miss.
Services I manage:
- SysAdmin & Virtualization: Expert management of Linux (Debian/RHEL), Windows Server, and VMware.
- Cloud Operations: Daily administration of GKE (Google) and AKS (Azure) clusters.
- Observability: Full system visibility via Grafana and Prometheus dashboards.
- FinOps: Cloud cost auditing and optimization to reduce bills.
- Continuity: Design of Backup and Disaster Recovery (DR) plans.
- Automation: Efficient maintenance using Ansible, Bash, and Python.
If you are looking for a problem-solver to guarantee system stability, let's talk.
