Timo Michiels

Experienced Linux Systems Administrator and Infrastructure Engineer with over 5 years of experience supporting more than 200 enterprise Linux environments. These include production, test, and development infrastructures in several African countries. I have a strong background managing essential Linux systems in high-pressure settings, including enterprise and MSP environments.

My responsibilities include ensuring uptime, resolving incidents, optimizing infrastructure, monitoring systems, managing patches, handling backups, and maintaining system stability. I have hands-on experience supporting large Linux server environments, including Red Hat Enterprise Linux, Oracle Linux, Ubuntu, and Debian, in both physical and virtual infrastructure. I am skilled in troubleshooting Linux issues, tuning performance, enhancing security, optimizing systems, providing networking services, managing virtualization, and implementing automation.

I have a proven track record of resolving complex infrastructure incidents independently, supporting mission-critical services under SLA pressure, and maintaining stable production environments across multiple client sites. I have strong exposure to Bash scripting, automation concepts, systems monitoring, backup technologies, and infrastructure support processes. I am recognized for my reliability, technical expertise, problem-solving skills, and my ability to quickly troubleshoot and stabilize enterprise systems.

Previous management has consistently supported my work quality, technical standards, and operational reliability.
