What I'm looking for
I am a strategic and solutions-driven IT Architect and Senior Systems Administrator with over 10 years of enterprise experience across Apple, Windows, and hybrid environments. My expertise lies in Apple technologies, JAMF Pro, AirWatch, and systems lifecycle management. I have a strong record of leading enterprise rollouts, designing scalable IT infrastructure, and optimizing end-user experiences.
In my recent role as a Sr. Client Systems Engineer at Penumbra Inc., I designed and managed JAMF Pro Cloud infrastructure for over 5,000 macOS/iOS devices. I architected system-wide deployment strategies and automated application packaging, which significantly improved provisioning workflows. My experience also includes spearheading cross-platform rollout plans at Allegiant Airlines, where I managed an MDM environment for over 20,000 devices, ensuring compliance and security across all platforms.
Throughout my career, I have demonstrated proven leadership in MDM architecture, security patching, and systems documentation. I am passionate about leveraging technology to enhance operational efficiency and user satisfaction, and I thrive in environments that challenge my technical and leadership skills.
