Infrastructure that
never fails.

Does your business rely on critical systems that simply cannot go down?

I help businesses ensure their critical systems are always available. From physical servers to cloud and Kubernetes environments, I design and manage reliable, secure and easy-to-maintain infrastructures.

All configuration versioned and reproducible with Ansible and Terraform. Deploy in minutes, not days.

Fast response

Incidents handled within 2 hours during business hours, with on-call support available.

Security by default

System hardening, security audits and best-practice compliance from the first deployment.

Continuous monitoring

Real-time dashboards with Grafana and intelligent alerts. Know what's happening in your infrastructure before it impacts you.

Why should you trust me

You work tirelessly for your business; I work tirelessly to ensure your infrastructure runs smoothly.

Real production experience

I manage critical systems. No beating around the bush: real environments with real consequences.

Thorough documentation

Everything I do gets documented. When the project ends, you have full control.

No vendor lock-in

I work with open-source technology and industry standards. No lock-in, no surprises.

Direct communication

No intermediaries or management layers. You talk directly to the person doing the work.

Built-in security

Security isn't an add-on. It's present from design to deployment.

Scalable from day one

Architectures designed to grow. What works for 10 users also works for 10,000.

Frequently asked questions

What people usually ask before we start working together.

What type of companies do you work with?
I work with SMEs, startups and mid-size companies that need solid infrastructure without maintaining a full-time internal IT team. Also with freelancers and developers who need well-configured servers.
Do you offer ongoing support or just one-off projects?
Both. I can handle a specific project (migration, hardening, server setup) or establish a monthly maintenance contract with a defined SLA and continuous monitoring.
Do you work remotely or on-site?
Primarily remote, which allows me to work with clients anywhere in Spain and Europe. For large-scale projects that require it, I can travel on-site.
What technologies do you typically use?
Linux in general, Kubernetes, Docker, Proxmox, pfSense/OPNsense, Ansible, Zabbix, Grafana, Wazuh and the ELK stack. For cloud, primarily self-hosted infrastructure or VPS on AWS.
What does the onboarding process look like?
First, a no-commitment call to understand your needs. Then I prepare a detailed proposal with scope, timeline and cost. No fine print.
