About

I'm a Computer Science student at Universitas Pertamina (Indonesia) with a passion for building things that live on the internet and in games.

I'm the sole technical architect behind Kaizen Network, an Indonesian Minecraft server network where I handle almost everything from game scripting and custom plugin development to full-stack web development and cloud infrastructure management.

I also sometimes explore AI/ML, tinkers with cybersecurity, or dabbles in IoT.
