Understand
Learn how the system works before changing it.
SAMIR EL MOUSAOUI · IT MANAGER
Systems, infrastructure and applied security.
I work as an IT Manager, with a broad focus on IT infrastructure, networking, Microsoft 365, automation, machine vision, and cybersecurity. I’m passionate about solving technical challenges, continuously learning, and sharing knowledge through clear and practical explanations.
01 · MINDSET
Knowledge matters when it can be applied.
Titles and certifications can demonstrate progress, but they are not the final objective. What matters is what remains after studying: what you understand, what you can explain and how you apply it to real problems.
I believe technology should be used with a clear purpose. A tool, platform or automation only makes sense when it improves a process, reduces friction or solves a real need.
Apply
Turn theory into decisions, solutions and real experience.
Simplify
Technology should reduce complexity, not create more of it.
02 · EXPERIENCE
Networks & Infrastructure
Switching, VLANs, fiber links, routing, Wi-Fi, virtualization and day-to-day site operations.
Microsoft 365 & Systems
User lifecycle, permissions, endpoints, collaboration services, Windows and Linux administration.
Automation
Scripts and workflows that reduce repetitive work without hiding how the process works.
Industrial Machine Vision
Cameras, lighting, inspection systems, configuration, integration and troubleshooting.
Cybersecurity
