What I'm looking for

I want to leverage my Linux/Windows administration and cloud infrastructure skills to optimize and secure IT environments—improving reliability through patch management and threat monitoring, and delivering scalable systems that support day-to-day operations.

I’m an experienced IT professional specializing in Linux and Windows administration, with a strong background in infrastructure engineering and system support. I focus on troubleshooting enterprise systems, enhancing system reliability, and ensuring security through effective patch management and threat monitoring.

I’ve managed VMware environments by monitoring servers for threats and vulnerabilities, applying appropriate patches, and supporting field operations to maintain security and operational efficiency. I also work across virtualization technologies and cloud platforms to deliver scalable IT solutions.

Alongside infrastructure work, I’ve provided freelanced deployment support and web development—deploying and troubleshooting applications on Windows Server, and building/maintaining websites with an emphasis on debugging, performance optimization, and SEO. I’m eager to leverage my system administration expertise to optimize and secure IT environments.
