About

I'm an Informatics Engineering student at Institut Teknologi Bandung (ITB)who is just starting my journey in technology. I have a growing interest in cyber security—especially learning through CTFs—as well as exploring modern web development using Next.js and TypeScript.

As a beginner, I love learning by doing. I am currently trying to build small web projects and solving basic security challenges to improve my skills step by step, rather than just reading theories.
