Mauricio M.

I help businesses troubleshoot Linux servers, deploy applications, and automate infrastructure tasks across cloud and on-premises environments. I'm a Senior Linux Systems Administrator with a background in enterprise Linux/UNIX operations and freelance infrastructure projects. My experience includes production troubleshooting, security patching, server deployments, virtualization, networking, and monitoring. What I can help you with: • Linux administration and troubleshooting — RHEL, Debian, Ubuntu, and SUSE; service failures, system configuration, updates, and connectivity issues. • Infrastructure automation — Bash scripts for application deployments, security configuration, and repeatable administration tasks; Python scripts for monitoring integrations. • Application hosting — Apache Tomcat, Java application runtimes, and scripted JAR deployment workflows. • Monitoring — Zabbix deployment with MySQL and custom data collection for monitoring tools. • Docker and cloud deployments — containerized services, Portainer, and application infrastructure on AWS, Google Cloud, and Oracle Cloud. • VPN, remote access, and self-hosted services — NetBird, MeshCentral, Nextcloud, UniFi Controller, and MyWorkDrive with Azure Blob Storage. My enterprise background includes L3 incident support, planned maintenance, ITIL-based change management, runbooks, and knowledge transfer. I bring that operational experience to freelance projects, with an emphasis on troubleshooting, maintainable configurations, and clear documentation. Certifications: • Google Cloud Certified — Professional Cloud DevOps Engineer • LPIC-1 — Linux Professional Institute I'm interested in both clearly scoped infrastructure projects and ongoing Linux administration engagements. Send me a brief description of your environment, the issue or project goal, and your timeline so we can discuss the scope.
