View certificateAbout
I graduated from Universitas Pertamina (Indonesia) in August 2026 with a bachelor's degree in Computer Science. My thesis implemented privacy features for online game platforms based on UU PDP. I build and operate web applications and game systems.
I'm the founder and sole full-stack developer behind Kaizen Network, an Indonesian Minecraft server network with 100,000+ registered accounts and 150 peak concurrent players. I own the TypeScript/Next.js applications, payment integrations, custom Java plugins and cloud operations from implementation to deployment.
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.
