Hello! Welcome to my personal website.
I am Justin Sepvian, an Informatics Engineering student at Institut Teknologi Bandung (ITB). This website serves as my digital workspace—a place where I document my learning journey, showcase my projects, and share my thoughts on technology.
My Focus Areas
My main interests lie at the intersection of two fascinating fields:
- Cyber Security: I enjoy learning about network vulnerabilities, cryptography, and solving Capture The Flag (CTF) challenges. The offensive and defensive aspects of security force you to understand how systems truly work under the hood.
- Web Development: I love building things. From modern frontend interfaces to secure backend architectures (like my project, CO-Pas), I enjoy the process of turning ideas into functional, real-world applications.
Why This Site?
I built this portfolio to force myself to learn in public. Theory from university is important, but practical application is where real growth happens. Whether it's setting up an isolated network attack simulation lab or writing a secure E2E encrypted pastebin from scratch, I learn best by building.
If you share similar interests, are looking for a collaborator, or just want to connect, feel free to reach out via email or LinkedIn.
Thanks for dropping by!
