About Me

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 go hand in hand — all about reading patterns and solving the right problems.

Most of my time now sits somewhere between lectures and the screen, where scientific logic meets the world of cybersecurity. Every line of code and every security vulnerability is an experiment that demands precision.

Outside of class, I keep my problem-solving sharp 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
Every problem gets broken down with logic and scientific thinking at its core.
Continuous Learner
Self-study, experimentation, and staying adaptable are habits I keep every day.
Creative & Technical
Years in design sharpened my visual instincts, and they carry over into everything technical I build.
Builder Mindset
Whether it's a website, a CLI tool, or a rough idea, I like seeing things go from concept to something real.
