About me

I am Christopher Pengalilla, a 7th-semester Computer Science (Informatics) student at the University of Surabaya, with experience in project management and team coordination. Currently, I am honing my cybersecurity skills through Capture the Flag (CTF) challenges, focusing on web penetration, cryptography, digital forensics, and many more. Passionate about optimizing workflows, solving problems, and enhancing productivity, I bring strong communication and technical skills to every endeavor.

While I still continue to learn and exercising cybersecurity skill through CTF challenges, I also build various application and software projects to enhance my programming skills. Beside that, I learn about cloud computing and its services, which I believe are essential skills in today's tech landscape.
