ABOUT

I'm an Informatics Engineering student at Institut Teknologi Bandung (ITB) with a deep passion for technology. My primary focus is on Software Engineering, building scalable and modern web applications, though I also maintain an interest in cyber security.

As a developer, I love learning by doing. I am currently building various web projects using modern stacks like Next.js and TypeScript, constantly pushing myself to write cleaner code and architect better systems step by step.
