A LITTLE ABOUT ME

Curious about systems.
Driven to build.

I’m an Information Technology student at Universitas Brawijaya interested in cryptography and blockchain. My public work includes a browser-based encryption app, tools for CTF creators and writeups, and hands-on experiments across the web.

I enjoy taking a technical idea and turning it into something people can use, test, and learn from.
