IT Analyst • Cloud, Linux & Infrastructure Operations

I’m Miguel Lopez, an IT professional with hands-on experience across support operations, cloud environments, endpoint systems, and technical troubleshooting.

I specialize in identifying root causes, resolving system issues, and restoring services efficiently, while continuously building deeper expertise in cloud and infrastructure operations.

I actively build real-world labs and projects to simulate production environments and strengthen my skills in Linux, cloud, and incident response.

• Cloud infrastructure (AWS & Azure)
• Linux system administration & troubleshooting
• Incident response & root cause analysis (RCA)
• Automation with Python & PowerShell
• Transitioning into Cloud / Service Operations roles

Simulated a real production outage using Amazon Linux + nginx to replicate high CPU degradation and service disruption.

• Identified abnormal CPU usage using top
• Isolated runaway process via ps aux
• Restarted services using systemctl
• Validated system recovery using curl and service checks

Skills Demonstrated:
Linux • Incident Response • Root Cause Analysis • AWS EC2 • Service Recovery
