I’m Martín. I manage infrastructure, connect operations and turn lessons learned into lasting improvements.
The same profile. The depth you need.
Getting it running again is not the end.
I want to understand why it failed.
End-to-end platform ownership.
Experience in production environments.
Processes, automation and applied AI.
Linux & Windows Server · Proxmox VE · Active Directory & SSO · Zabbix HA · PostgreSQL with VIP · Grafana · GLPI · Hardening
3D Observer develops stereoscopic computer-vision systems to detect birds and reduce their risk of collision at wind farms.
My work is in the IT/OT infrastructure, monitoring and operations supporting that activity.
My journey in the companyEvery step adds context. Every challenge brings a better way to solve the next.
May 2025 — present
From an internship to responsibility for support and operations. A progression built on working with real infrastructure.
About the companyI coordinate support operations and critical incidents while administering and evolving IT/OT infrastructure. I manage the entire Zabbix platform and automate processes and alerts.
Administration of Linux, Windows Server, Proxmox and Active Directory. Work across availability, monitoring, identity, hardening and technical documentation.
Zabbix monitoring, L1/L2 incident diagnosis and resolution, coordination with technical teams and direct communication with customers.
First experience with the systems and monitoring team. Infrastructure tasks and security testing, followed by joining the company after the internship.
Independent projects
A personal, self-taught project running private game servers. Design, deployment, maintenance, resource integration, user support and community coordination. My first practical experience of the complete service lifecycle.

Knowledge developed through projects, education and hands-on work; not all at the same depth.
Education lays the foundations. Working with real systems brings the next questions.
Enseñanzas Profesionales Sorolla
The foundations: operating systems, networks, hardware, technical support and security. Understanding each component to understand the whole.
Enseñanzas Profesionales Sorolla
From foundations to infrastructure: Linux and Windows Server, network services, databases, virtualization, scripting and security. Studies combined with hands-on professional experience in production.
MEDAC
The next educational step. I aim to connect systems administration with data analysis and automation for IT operations. Planned start in January 2027.
My cybersecurity training complements the administration and protection of infrastructure.
