About
As a System Administrator 3 at General Dynamics Information Technology, I support the installation, configuration, and maintenance of Linux web, application, and database servers for various federal clients. I ensure the security, reliability, and performance of the systems, and troubleshoot any issues that arise. I also collaborate with other IT professionals and stakeholders to provide technical guidance and solutions. I have 24 years of Information Assurance and Technology experience, within various roles in the military & civilian sectors. I have worked as a Senior Service Support Specialist, Telephone Control Officer, Video Teleconference Manager, and Senior Systems Administrator for different organizations. I have also served as a Military Instructor of Cisco Information Technology Essentials, sharing my knowledge and skills with others. I hold an Associate of Arts degree in General Studies from University of Maryland Global Campus, and I am Microsoft Certified in Server 2012. I am passionate about learning new technologies and enhancing my expertise in Linux, Windows, Cisco, and VM related systems.
