Cybersecurity student · Builder · Peer leader
I build secure systems and explain the work clearly.
I'm Julian Arceo. I study cybersecurity at Purdue University Northwest and work in access control and security analysis. I learn by getting involved, asking questions, and building things for myself.

Still learning.
Always building.
I learn best
by doing.
I like figuring out how systems work. Once I understand one, I usually want to improve it, document it, and show someone else what I learned.
I'm earning a B.S. in Cybersecurity with a Computer Science minor at Purdue University Northwest. I'm also in the Honors College and have made the Dean's List each semester. At work, I'm gaining experience in healthcare access control and security analysis.
Outside class and work, I run my own home server, compete in cyber defense events, mentor other students, and build websites. I've also taught cybersecurity to younger students and presented tools such as John the Ripper.
See the path so farWhat I actually
work on.
Security work I can explain
My roles at Powers Health and the Indiana Cyber Network are teaching me how security decisions affect both systems and the people using them.
A server I built myself
Project Citadel is my home lab. I use it to practice Linux, Docker, networking, backups, and security with real services.
Showing what I learn
I like taking something technical and turning it into a demo, presentation, or website that people can actually follow.
Project Citadel
Project Citadel is the home lab I built to practice Linux, Docker, networking, and security. It hosts real services that I use, maintain, troubleshoot, and continue improving.
