About

After years of experience shadowing a current engineer in the field, I have grown to love learning about Networking and Storage as well as physical hardware. I am a detail-oriented Computer Information Systems student at Lander University with a 4.0 GPA, specializing in Cybersecurity and Networking. I have hands-on experience in IT support, network troubleshooting, and front desk operations, complemented by strong programming skills in Python, Java, HTML, JavaScript, C, and C++. My professional experience spans from managing high-volume customer service environments to performing complex IT migrations for healthcare systems. I am pursuing opportunities in cybersecurity, network administration, and IT support where I can apply my skills, certifications, and passion for secure, efficient technology solutions.
