About Me

My journey in tech began at Murray State University in Kentucky, where I pursued a Computer Science major. During my studies, I discovered a deeper passion for networking and cybersecurity, leading me to transfer to Purdue University to specialize in Cybersecurity.

As a student, I've always wanted to help others with what I love most—computers and IT. Whether troubleshooting network issues, securing systems, or developing web applications, I strive to strengthen digital infrastructure and protect critical data.

Now, I'm actively seeking a Summer 2025 Cybersecurity Internship to gain hands-on experience in network security, virtualization, and secure software development while collaborating with innovative teams to build a safer digital future.
