Infrastructure Management: Maintain and optimize high-availability systems, including virtual machines (VMware/Hyper-V), databases, and cloud environments (Azure/AWS).

Automation & Scripting: Develop scripts (Python, PowerShell, Bash) to automate repetitive tasks and improve system efficiency.

Security & Compliance: Implement advanced security protocols, manage firewalls, and ensure the organization meets industry compliance standards.
