Curiosity-Driven, Science-Backed

I'm Devandra El Syadam, a Physics student at UIN Jakarta who started out in the world of design at SMKS Sasmita Jaya 1. It might seem like an unusual path, but to me, Design, Physics, and Technology are one package — all about understanding patterns and solving problems.

These days, I spend most of my time between lectures and the screen, combining scientific logic with the world of cybersecurity. Every line of code and every security vulnerability is an experiment that demands precision.

Outside of class, I actively sharpen my problem-solving through CTF (Capture The Flag) platforms and various cybersecurity challenges, particularly in log analysis, digital trails, and forensic investigation to understand and secure digital systems.

Scientific & Analytical
Approaching every problem with logic and scientific methods as the foundation.
Continuous Learner
Self-study, experimentation, and adaptation are a core part of my daily routine.
Creative & Technical
A design background gives me visual sensitivity that complements my technical skills.
Builder Mindset
I enjoy building things — from websites and tools to ideas that become real products.
