What I'm looking for

I am looking for a role that fosters collaboration, innovation, and continuous learning in IT.

I am a dynamic and solutions-focused IT professional with over 10 years of hands-on experience in Citrix virtualization, Windows Server administration, and end-user support. My career has been marked by a proven success in troubleshooting Tier 2/3 escalations and managing large-scale VDI deployments. I have a strong commitment to system optimization and automation, ensuring seamless user experience delivery.

In my current role as a Senior Citrix Engineer at NYU Langone Health, I lead the architecture for Citrix XenApp/XenDesktop infrastructure, designing and maintaining enterprise-grade solutions for high availability. I have developed PowerShell scripts that enhanced performance and reduced application launch times by 20%. My experience also includes providing mentorship to junior staff and collaborating with vendors to resolve high-level escalations, showcasing my ability to drive excellence through ITIL-aligned practices.
