Summary

IT systems professional certified in CompTIA A+, Network+, and Security+, with an Associate of Science in Business Administration and a second Associate in Information Technology in progress. I build and operate a self-hosted virtualization environment that hosts web applications in daily use, and I take projects from idea to a deployed, maintained system. Comfortable across hardware, Linux administration, networking, security practices, and application deployment. I use AI-assisted development workflows for application implementation, combined with hands-on testing, deployment, infrastructure management, troubleshooting, and technical support.
