04 / ABOUT

Curious by
construction.

I'm a Computer Science and Mathematics student at Bina Nusantara University interested in building technology across software engineering, artificial intelligence, data, cloud systems, and digital products.

I enjoy moving between different layers of a project — from understanding the problem and designing the system to building applications, experimenting with machine learning models, analyzing data, and turning ideas into usable products.
