About

I graduated from Universitas Pertamina (Indonesia) in August 2026 with a bachelor's degree in Computer Science and a thesis on UU PDP compliance for online game platforms. I love building things that live on the internet and in games.

I'm the founder and sole technical architect behind Kaizen Network, an Indonesian Minecraft server network with 100,000+ registered accounts and 150 peak concurrent players. I handle almost every technical thing there, from game scripting and custom plugin development to full-stack web development and cloud infrastructure management, at 99.9% uptime.

I also founded Packvertise, an ad-on-packaging startup that reached the top 7 of 31 teams at UPER CASE IB 2025. Outside of that, I explore AI/ML, dabble in IoT, and do security research on the side, including a Microsoft-credited vulnerability find in Visual Studio Code.
